If your ISP requires authentication for email sending and receiving, use these values:
mail server = pop3
incoming pop3 email server = mail.rc.net
outgoing smtp email server = whatever smtp outgoing email server name your ISP gives you to use.

Check the box that says "my server requires authentication" or "Use name and password" and then enter your ISP-provided "account name" and "account password".

Note: You may have to set the server port number for outgoing mail (SMTP) to a different number such as 465.
Note: You may also have to check the box that says "this server requires a secure connection" for the outgoing mail (SMTP) server. Do not check that same box for the incoming (POP3) server.

Do Not Check the box that says "Log on using Secure Password Authentication".

If you are getting "send errors" or "553 errors", you may need to authorize your rc.net email address with AT&T. (AT&T has been randomly implementing this requirement.)
The steps to do this are:

  • With your browser, go to www.att.net
  • Click on "Mail" and sign in using your AT&T email address and password.
  • Click the "gear" icon in the upper right area of the page
  • Click on "Mail Options" in the pulldown menu that appears
  • Click on "Mail Accounts" in the menu on the left side of the screen
  • Click the "+add" button
  • Fill in the name (your display name, anything is fine) and your rc.net email address and click "continue"
  • In the new window that opens up, don't fill in any fields, just click on "SKIP THIS STEP, SETUP TO SEND ONLY" at the bottom
  • Now check your rc.net email for the message from AT&T, follow the clickthrough step there, and your email address will now be authorized to send through AT&T's outgoing email server
