Yahoo! Mail is a web mail service provided by Yahoo!. It was inaugurated in 1997, and, according to comScore, Yahoo! Mail was the second largest web-based e-mail service with 273.1 million users as of November 2010.^[1]

Currently, Yahoo! offers three versions of Yahoo! Mail. The traditional "Yahoo! Mail Classic" continues the availability of the original interface introduced in 1997. A new version introduced in 2005 included a new Ajax interface, drag-and-drop, improved search functionality, keyboard shortcuts, address auto-complete, tabs, and more. In October 2010 Yahoo! released a new beta version of Yahoo! Mail,^[2] which included a new design, improved performance, improved search functionality, and improved Facebook integration.^[3] In May 2011 beta testing for the new version stopped, and it became the default interface for Yahoo! Mail.^[4]

In early 2008, Yahoo! started offering unlimited mail storage to its users, in response to heated competition in the free-web mail market segment.^[5]

On June 27, 2009, Yahoo! Messenger was integrated with Yahoo! Mail.^[6]

History

The growth in the number of Internet users eventually boosted the e-mail technology, but also created a very competitive environment where the winner was the first company to launch a successful e-mail service and attract potential users. E-mail became one of the most important features of a Web company as it would mean regular visits from e-mail users to the website.

When Hotmail and Mirabilis (the creator of the instant messenger ICQ) were looking to be bought, Yahoo! was the first company to which both made offers. Yahoo!, however, passed on both companies as they were too expensive for Yahoo! at that time. In the end, Microsoft ended up buying Hotmail for $400 million and AOL bought Mirabilis for $288 million.

Yahoo! made a deal with the online communications company Four11 for co-branded white pages. Marvin Gavin, who worked at Four11 as director of international business development said, "We always had a bias about being acquired by Yahoo! They were more entrepreneurial than Microsoft. We had a great cultural fit – it made a lot of sense." The real point in acquiring Four11 was that in March 1997, the company had launched Rocketmail, a webmail system that could be offered to users. In the end, Yahoo! concluded a deal with Four11 for $96 million. Yahoo! announced the acquisition^[7] on October 8, 1997, very close to the time that Yahoo! Mail was launched.^[8] Yahoo! Mail resulted from an acquisition rather than internal platform development because, as Healy said, "Hotmail was growing at thousands and thousands users per week. We did an analysis. For us to build, it would have taken four to six months, and by then, so many users would have taken an e-mail account. The speed of the market was critical."

The transition to Yahoo! Mail was not easy for many Rocketmail users at first. Yahoo! released various help pages to try and help these users.^[9] Soon after, on March 21, 2002, Yahoo! cut free software client access and introduced the $29.99 per year Mail Forwarding Service.^[10] Mary Osako, a Yahoo! Spokeswoman, told CNET, "For-pay services on Yahoo!, originally launched in February 1999, have experienced great acceptance from our base of active registered users, and we expect this adoption to continue to grow."

During the summer of 2002, the Yahoo! network was gradually redesigned. On July 2, Yahoo.com was redesigned and it was announced that other services like Yahoo! Mail would enter the same process.^[11] Along with this new design, new features were to be implemented, including new navigation tools, such as drop-down menus in DHTML and different category tabs, and a new user-customizable color scheme.

In November of the same year, Yahoo! launched another paid service: Yahoo! Mail Plus.^[12] Yahoo! Mail Plus offered a number of new features, including:

• 25 megabytes of e-mail storage
• 10 megabyte message size limit
• Ability to send up to 10 attachments per e-mail
• POP Access and Forwarding
• Archiving of e-mail messages to a hard drive for offline access
• Ability to send messages from Yahoo! Mail using other e-mail domains
• 200 blocked addresses and 50 filters to help screen unsolicited e-mails
• No promotional taglines in messages
• No account expiration.

The launch of Yahoo! Mail Plus is part of Yahoo!'s strategic initiative to offer premium services that deliver innovative, reliable and relevant services to consumers", said Geoff Ralston, senior vice president, Yahoo! Network Services, and creator of the original Yahoo! Mail technology in 1997. "In just five years, Yahoo! Mail has grown from one million to tens of millions of users, illustrating how consumers have made e-mail an essential part of their daily lives. Through Yahoo! Mail Plus, Yahoo! continues to demonstrate leadership and innovation by offering consumers the industry's most complete and powerful e-mail solution.

—^[12]

On April 1, 2004, Google announced a free webmail with 1 gigabyte of storage. Though Gmail, Google's e-mail service, offered a large amount of storage, its invitation-only accounts kept the other webmail services at the forefront. Most of the major webmail providers like Yahoo! Mail, Hotmail, and AOL followed Google's lead and increased their mailbox storage considerably. Yahoo! was the first provider to announce 100 MB of storage for basic accounts and 2 GB of storage for premium users.^[13] Determined not to lose customers, Yahoo! Mail then countered Hotmail and Google by increasing the storage quota of its free e-mail accounts to 1 GB, and eventually removing a storage limit altogether and allowing unlimited storage.

On July 9, 2004, Yahoo! acquired Oddpost, a strong webmail offering that simulated a desktop e-mail client like Microsoft Outlook. Oddpost had new innovative features such as drag-and-drop support, right-click menus, RSS feeds, and a preview pane, but it also had incredible speed, using e-mail caching to shorten response time, and many of these features were incorporated into an updated Yahoo! Mail service.^[14]

On August 30, 2007, Walter Mossberg wrote in the Wall Street Journal that Yahoo! would be releasing the new version over the next few weeks.^[15] On September 17, 2010 Yahoo showed off the new Mail program to reporters.^[16]

Yahoo! Mail Classic

Yahoo! Mail Classic was the original interface for Yahoo! Mail. Although the default interface is now "Minty", Mail Classic is still available for users who prefer to use the legacy style interface, advanced search function (that does not exist in the "New Yahoo Mail") or for those whose computers don't match the system requirements for the New Yahoo Mail. In March 2009, Yahoo! Mail Classic integrated Yahoo! Messenger into its interface so people can chat and e-mail at the same time. Then in mid-2011, Yahoo began a new initiative to implement and unsolicited redirect of Classic Mail users to the new Yahoo Mail. However, users can still revert back to Classic Mail by explicitly launching Classic Mail at the following URL:

Yahoo! Mail (2007 release)

(2007 release)

In September 2005 Yahoo! began beta testing a significantly enhanced version of their e-mail service which was designed to mimic a heavy mail client like Outlook. It featured drag-and-drop capabilities, advanced search, advanced keyboard shortcuts, address auto-complete, tabbed emails, and more. The new Yahoo! Mail also came with an integrated version of Yahoo! Messenger; as a result, users were able to chat with Yahoo! Messenger and Windows Live Messenger contacts while reading their e-mail. On August 26, 2007, the new Yahoo! Mail came out of beta period, and became the default interface.

Underlying technologies

The new Yahoo Mail was based on Ajax scripting acquired from Oddpost, (JavaScript and XML), along with new philosophical approaches to e-mail, including the Oddpost design philosophy (which Google made heavy use of in Gmail): Given that the new Yahoo! Mail was based on Oddpost, it featured the same underlying code base, including the implementation of this design concept to minimize the amount of data sent during an e-mail session by creating a JavaScript UI engine on the client side and sending "Datapacks" instead of reloading the whole interface on every click like a traditional webmail service ^[17] (e.g. traditional Yahoo! Mail). This made the service much faster than its counterparts. However, unlike Oddpost, the new Yahoo! Mail ran on a variety of operating systems and browsers, and ran perfectly under Internet Explorer 7 and Firefox. On February 13, 2008, Yahoo! announced on the Yahoo! Mail blog that it would begin supporting version 3 of the Mac OS X default browser Safari, as well as the Mac versions of Firefox.^[18]

Introduction

The public beta of the new Yahoo! Mail began in late 2006. In November 2006, Yahoo! announced plans for integrating Yahoo! Messenger functionality with the New Yahoo! Mail interface.^[19] This service was deployed in March, 2007. Public and critical reaction to the new product was positive,^[20] although a number of users encountered speed issues. Each update to the new Yahoo! Mail included significant speed improvements, and the new Yahoo! Mail team was still focused on improving speed issues. For example, earlier versions featured a loading screen every time you accessed mail. However, with various updates the new Yahoo! Mail appeared immediately, without any loading screen. On August 26, 2007, the new Yahoo! Mail left beta. The announcement was made on the Yahoo! Mail blog^[21] by John Kremer, Vice President, Yahoo! Mail and the major improvements related to intelligent shortcuts, SMS Messaging, and improved search. The final version was released on October 9, 2007.

Features

Some of the new or improved features included in the new Yahoo! Mail were:

• Yahoo! Calendar integration
• Yahoo! Messenger integration
• Windows Live Messenger integration
• SMS Messaging in certain countries
• Keyboard shortcuts
• Unlimited storage
• Improved search facilities
• Applications (Piknic, Flickr, Wordpress and more)

In addition, an Easter egg was added called a Subject-O-Matique. This hidden feature displays a random message in the subject line when the subject button is clicked. The messages range from cultural references ("I AM the walrus") to sarcastic ("If you don't tell lies, at least you don't have to remember what you have said.") to unusual and outlandish ("the art of driving a giant, nuclear powered duck"). On December 15, 2008, Yahoo! Mail introduced features to make it more social.^[22][23]

Yahoo! Mail (2011 release)

Screenshot of the current Yahoo! Mail.

The new version of Yahoo! Mail, codenamed "Minty", was first announced on 16 September 2010 on the Yahoo! Mail Blog.^[24] It included a new interface, enhanced performance, improved Facebook and Twitter integration, the ability to watch YouTube videos straight from your email, improved search, and more.^[25]

It is possible to switch back to the old version by disabling javascript in any browser and trying to load yahoo mail. Click return to a previous version, enable javascript again and you will have the previous version back.

The first public beta began on October 26th, 2010.^[26] In May 2011 beta testing for the new Yahoo! Mail stopped, and the new Yahoo! Mail became the default interface for Yahoo! Mail.^[4]

As the new Yahoo! Mail became mandatory for users, a number of previously satisfied users of Yahoo! Mail started to report slow typing speeds with the new Yahoo! Mail,^{[citation needed]} running contradictory to Yahoo!'s claims that the new Yahoo! Mail would perform "2x" faster. Yahoo! offered no resolution to the problem as of September 12, 2011, and continued to advertise that Yahoo! Mail "provides performance that is 2x faster than the previous versions of Yahoo! Mail" and runs at "lightning speed."^{[citation needed]} Further slowing down user productivity, users cannot copy and paste email addresses from the sender box but must navigate to the Contacts tab and search for a contact to be able to copy and paste an email address. This is because now recipient email addresses convert to the name of the recipient highlighted inside a box, without an immediate option for accessing the email address to copy and paste like in traditional email clients.^{[citation needed]} Although it is not mentioned, upgrading to the new version disables the use of the secondary addresses provided in the previous version. Thus users will not receive emails sent to a secondary address anymore. The new interface overrides the browser's right mouse button (e.g., making functions such as opening mails in new tab windows unavailable).^{[citation needed]}

Features

Yahoo! Mail has the following features:

Free version

• Email storage capacity: unlimited^[27]
• Email attachment limit: 25 MB (up to 100 MB via the built-in 'Attach Large Files' app)^[28]
• Account expiry on inactivity: 4 months
• Supported protocols: POP3 in Asia or via YPOPs!, IMAP via IMAP proxy or via Zimbra, SMTP, Mail Forwarding in some countries (but not in the US). Current and new accounts can not order the free POP3 / forwarding service – attempts give a currently not for sale error.
• Ads: yes

• 100 filters to automatically sort incoming messages (200 filters for the Plus version)
• Protection against spam and viruses. (See: DomainKeys)
• Advertising is displayed on the screen while working with the e-mail account. Text ads are not within the e-mails themselves, and they are now added to the footer of outgoing messages, as of February 2011.
• Accounts not logged into for four months get deactivated (the account can be retrieved but all stored data, such as e-mails, are lost).
• Early in 2006, Yahoo! Mail introduced aliases to its repertoire of features. Users could now add a (single) alias username containing a dot character for a pre-existing account.
• The Chinese version of Yahoo! Mail^[29] offers 3.5 GB quota and 20 MB attachments.^[30]
• Some users get features added if they are long time users.
• Latest beta of Yahoo! Zimbra desktop allows for all Yahoo! users to use the software

Users from countries where there is a web browser access restriction can get around it by using software that simulates a POP3 server to which the e-mail application connects. YPOPs! and FreePOPs are examples of free software applications that allow e-mail clients access to webmail (including Yahoo! Mail) services through POP3.

Another way of getting POP3 access without signing up for the paid mail plans is signing up for Yahoo! Delivers, a service which sends the user promotional e-mail messages. According to the Yahoo! Mail help pages,^[31] "Yahoo! offers POP access to Yahoo! Mail as a free feature exclusively for Yahoo! Delivers members". However, this applies only to users of Canadian^[31][32] Yahoo Mail with "@yahoo.ca" extension of their mail.

Free IMAP and SMTPs access

It is possible to get direct IMAP access. Yahoo! operates IMAP and secure IMAP servers (imap.mail.yahoo.com in particular), which are globally accessible. According to the Yahoo! company, IMAP access is only allowed for smart phones on mobile networks, not desktop computers.^[33]

For regular internet users, an IMAP proxy like Yahoo IMAP Connector^[34] may be needed to connect to the Yahoo! IMAP servers. Alternatively, modifications are available for some email clients, such as Mozilla Thunderbird and Mutt.^[35] The proxy method is required to access Yahoo email through commercial email clients like Microsoft Outlook.

It is also possible to send mail through mail clients as Yahoo! also operates an SMTP server (smtp.mail.yahoo.com). It is necessary to enable SSL through port 465. For IMAP and SMTPS access the username is the user's Yahoo! Mail address and the password is the same as for webmail access.

Mac OS X users can directly set up an IMAP account in Apple Mail 4.4. After entering a full name, email address and password, hold down the Option key. The Create button will change to Continue, allowing one to manually configure the account settings.

Apple Mail 5.0 included with Mac OS X Lion supports easy and direct IMAP account setup.

Business

Yahoo! Business E-mail is a combination of all of their e-mail services with 10 distinct accounts each with the same features of the plus version and personalized domain name and e-mail address. The main, the cover page is tailor-made and changing time to time, for example: "There's a new master of the digital universe. YOU". Accounts can be managed by an administrator. There is $25 set-up fee and $9.99 monthly fee to use this service. Yahoo! is still working out how to allow their business mail clients to access their e-mail accounts from certain mobile smart phones and PDAs. According to Yahoo!'s website, customers can currently access business e-mail only via BlackBerry. Yahoo! says it plans to make its service compatible with more devices in the future. Yahoo!'s Business mail is also not compatible with the latest releases of Leopard/Safari. It is compatible with the latest releases of Safari – but only when running on OS X Tiger.

• Unlimited Mail Storage
• 10 E-mail quota.
• Additionally, a user can pay $35 per year to have up to five custom e-mail addresses and a domain name.
• Classic Yahoo! Mail underlines addresses and phone numbers in e-mails and allows the user to add them to the address book.

Ymail and Rocketmail

Yahoo! Mail Vice President John Kremer on June 19, 2008 announced the tripling of the size of its free online e-mail service with the launching of 2 domains as options for its 266 million users of "@yahoo.com" addresses: the new, simpler e-mail addresses ending in ymail.com and rocketmail.com. Rocketmail has a "hip retro feel" since it is a resurrected e-mail address of a 1997 Yahoo service.^[36] E-mail under the ymail and rocketmail domains will offer all the same features as the Yahoo domain, with an unlimited amount of storage capacity, with ability to instant message from within their e-mail inbox and spam and virus protection.^[37][38]

Spam policy

Like most free Webmail providers, Yahoo! Mail is often used by spammers to provide a "remove me" e-mail address. More often than not, these addresses are used for the express purpose of verifying the recipient's address—thus opening the door for more spam. However, Yahoo! does not tolerate this practice. It terminates accounts connected with spam-related activities without warning, and spammers lose access to any other Yahoo! services connected with their ID under the Terms of Service.^[39][40]

In February 2006, Yahoo! also announced their decision (along with AOL) to give some organizations the option to "certify" mail, by paying up to one cent for each outgoing message, allowing the mail in question to bypass Yahoo's and AOL's inbound spam filters.^[41]

In April 2011, Yahoo Mail began rejecting spam reporting, that involves sending a copy of the spam with full headers, to Yahoo's abuse department via the email address abuse (at) yahoo.com, and the response email for those that did was to use a form instead. However, that requirement to use a form is prohibited by several Internet RFCs, and the availability of abuse (at) example.com (in this case abuse (at) yahoo.com) is required by the Invariants clause of RFC 2142 as the domain has a mail server and 'MX Record'. Their claim was that their 'standard' was 'better' than the Internet standards referred to.

Filters

In 2002, in order to prevent abuse, Yahoo! Mail had filters that changed certain words (that could trigger unwanted Javascript events) and word fragments into other words. "Mocha" was changed to "espresso", "expression" became "statement", and perhaps most damaging, "eval" (short for "evaluation") became "review". The widespread unintended effects of this can be seen by using search engines to find such nonsensical terms as "prreviewent"(prevalent), "reviewuation"(evaluation) and "medireview"(medieval).

When asked about these changes, Yahoo! explained that the changed words were common terms used in Web scripting, and were blacklisted to prevent hackers from sending damaging commands via the program's HTML function.

As of February 7, 2006, the Yahoo! Mail filters no longer substitute certain words for others. Although the change may have occurred prior to this date, Yahoo! Mail now prefixes an "_" (underscore) to certain suspicious words and word fragments.

Sending a test e-mail from a non-Yahoo! Mail account to a Yahoo! Mail account with the words "Mocha", "eval", "Javascript", and "expression" in a sentence resulted in the Yahoo! Mail filters prefixing an "_" (underscore) to those words, resulting in "_Mocha", "_eval", "_Javascript" and "_expression". This prefixing removes the threat of the words acting as commands via the program's HTML function by rendering them as non-commands or unrecognizable commands. As of June 9, 2006, only the terms "expression" and "javascript" were prefixed with an underscore ("_").^{[citation needed]}

There is also offered a spam filter called SpamGuard and an ability to set up custom filters. One problem that can be encountered is that the spam filter is applied before any custom filters the user creates. This results in some e-mails that should have been directed to the Inbox or some other folder to be sent to the Bulk folder instead.

Greylisting

Incoming mail to Yahoo! addresses can be subjected to deferred delivery as part of Yahoo!'s incoming spam controls. This can delay delivery of mail sent to Yahoo! addresses without the sender or recipients being aware of it. The deferral is typically of short duration, but may extend to several hours. Yahoo! does not specifically document this policy in detail, although some information is available.^[42][43]

Controversy

Shi Tao arrest

In 2004, Yahoo!'s Hong Kong office provided technical information to the Chinese authorities about the account of journalist Shi Tao. Shi Tao was subsequently sentenced to ten years' imprisonment for "leaking state secrets".^[44] Yahoo! was criticized by Reporters Without Borders for acting as a "police informant" to increase its profits.^[45] In August 2007, the US Congress began an investigation into Yahoo!'s handling of the case,^[46] with Yahoo! founder Jerry Yang testifying in a hearing before Congress.^[47] On November 6, 2007, the congressional panel criticized Yahoo! for not giving full details to the House Foreign Affairs Committee the previous year, stating it had been "at best inexcusably negligent" and at worst "deceptive";^[48] Representative Tom Lantos described its executives as moral "pygmies".^[49] Yang responded that Yahoo! no longer controlled its Chinese operations, and was collaborating with human rights groups to formulate ethical code for technology companies.^[50]

In a February 2006 hearing, Yahoo! executives swore that they had no information about the nature of the investigation. Some months later, it was discovered that the document provided to Yahoo! China on April 22, 2004 by the Beijing State Security Bureau stated, "Your office is in possession of the following items relating to a case of suspected illegal provision of state secrets to foreign entities." ^[51]

On November 13, 2007, Yahoo! settled with Shi for an undisclosed sum.^[52] As of May 2011, Shi remains in prison.

Username bans

On February 20, 2006, it was revealed that Yahoo! Mail was banning the word "Allah" in e-mail usernames, both separate and as part of a user name such as linda.callahan.^[53] Shortly after the news of the "Allah" ban became widespread in media, it was lifted on February 23, 2006. Along with this action, Yahoo! also made the following statement:^[54]

We continuously evaluate abuse patterns in registration usernames to help prevent spam, fraud and other inappropriate behavior. A small number of people registered for IDs using specific terms with the sole purpose of promoting hate, and then used those IDs to post content that was harmful or threatening to others, thus violating Yahoo!'s Terms of Service. 'Allah' was one word being used for these purposes, with instances tied to defamatory language. We took steps to help protect our users by prohibiting use of the term in Yahoo! usernames. We recently re-evaluated the term 'Allah' and users can now register for IDs with this word because it is no longer a significant target for abuse. We regularly evaluate this type of activity and will continue to make adjustments to our registration process to help foster a positive customer experience.

Search function failure

Since the beginning of 2008, many users have experienced a failure of the search function whereby it either fails to retrieve any messages, or (occasionally) just a small subset. In most cases, it is due to a corrupt index associated with the specific account. A request to the Yahoo! Mail support team asking for a "rebuilt index" usually suffices to fix that error.^[55]

In some cases it appears that the search function will stop indexing new e-mails. Old e-mails can be searched, but any new ones added to the inbox will not be added to the search index.

Yahoo support said that more than 2,000 messages can create a problem. Users who retain the old mail format can still have access to the full mail search function.

NNFMP

NNFMP is an internal protocol not recognised by IANA or the RFC's. Yahoo uses this protocol to internally route e-mail traffic across their network. The acronym stands for "Newman No-Frills Mail Protocol". It's a simple, high-performance protocol comparable to QMTP.
