BT Broadband - e-mail settings (getting e-mail to work)

f you have BT Broadband (this is not necessarily the same as having broadband on a BT line) you can set up Outlook or Outlook Express or similar programs to send and receive e-mail. But for this to work, you must have a BT Yahoo! account. This is normally set up by BT when your broadband order is processed, and BT should have told you your Yahoo! username and password. This will be in the form someone@btinternet.com or someone@btopenworld.com and is not the same thing as your ADSL logon password (which may look like someone@btbroadband.com). Nov 7th 2008: I had had recent reports that BT has started using BT Yahoo! logon details as the ADSL logon, so I suppose it's possible that some people may have valid ADSL logon details which end in @btinternet.com. Very confusing.

Note that the login name for your broadband line (example: someone@btbroadband.com) is not an e-mail address, and will not work as one. (But see above.)
First log in to BT Yahoo!² and check that your BT Yahoo! login name and password actually work. There are lots of help pages there to show you how to set up your e-mail program. See, for example, this.
To set up a BT Internet account with Outlook 2010, see my page here.
In summary:

• The POP3 server (incoming mail) is mail.btinternet.com
• The SMTP server (outgoing mail) is also mail.btinternet.com
• Both need your BT Yahoo! email address and password; you will have to tell your e-mail program that the SMTP server requires authentication.
• The SMTP server can use either port 25 or port 587.

The most common fault is to provide your ADSL username and password when your BT Yahoo! username and password is what's required.
