MailServerList

The Mail Server List is a public domain list of email providers and the correct configuration for their mail servers. It is designed to make autoconfiguration of email clients as easy as giving name, email address and password.

The List is here. You must read this page before you edit it. By editing it, you place your contributions in the public domain (insofar as copyright can apply to collections of facts).

Please insert new entries in Unicode code point ('alphabetical') order by Provider Name (Field 1).

If possible, please test the config before submitting it.

Formatting Notes

• Place a question mark in any field for which you do not know the value. Leave the field blank if you know that there is no value. "No" and blank are equivalent for boolean fields.
• Do include data for major providers which don't offer POP or IMAP (e.g. Hotmail). Clients can then inform the user of this.

Formatting notes for particular fields

See also the formatting instructions at the head of each column.

• Short Name (Field 4): The common, short name of the email service. If it has no shorter name, leave blank.
• Preferred (Field 5): If the provider offers multiple mail access methods, which one is better. Leave blank if there is no reason to prefer one over the other except for the technical merits of each protocol.
• DNS Names (Fields 6, 11, 16) : Include port numbers after server names (separated by a colon) only if non-default for (service + encryption type). But do check if port 587 is supported for SMTP and, if so, list it; it’s preferable to 25.
• Encryption (Fields 7, 12, 17): SSL is SSL 3, TLS is TLS 1. Don't put anything if the server only supports STARTTLS; it's no good for security.
• Usernames (Fields 9, 14, 19): "email" for whole address, "localpart" for local part (e.g. fred in fred@foo.com), or "prompt (example)" to get the client to prompt, giving the example "example".
• Enable URL (Fields 10, 15): Some providers do not provide IMAP or POP service by default, but require it to be enabled via a web UI. Paste the URL (for a logged-in user) for the relevant page here, and the application can prompt the user to visit it.

Using the List

• You may use the list for any purpose. Good community members are expected to contribute back any improvements they make to the list.
• Entries in the list may move around; the unique identifiers are the individual mail domains (note: not the whole field contents) in field 2.
• Columns may also move around if we find more data is required. Field numbers are guaranteed not to change. You can find the Field Number row because it is the row identified by "Field Number" in column 1. Use these numbers to recognise the columns.
• The number of header rows may also change. The data starts after the marker DATA_STARTS_BELOW_THIS_LINE.
