My old Thunderbird email account was with Time Warner, SC.RR.com. My new account (second account) is with AT&T, ATT.net.

In my old account I could assign a name to a list of several email accounts, put the lists name in the BBC: and send the email to all on the list. My new account will not accept the name of a list. It insists on the format for a single email account. I tried creating a new list after closing the old account and opening the new, but the results were the same.

How do I get 'list' to work on my new ATT account?

Does the list description include spaces? If so, try to use a name without spaces or replace spaces with "_", there has been a bug about this reported as Bug #1060901. If you have an account on Bugzilla, please consider voting for that issue.

Several other people have sent in the similar support requests to yous, noting this happened after they upgraded to version 31.1.

The exact error message is: XXXX is not a valid e-mail address because it is not of the form user@host. You must correct it before sending the e-mail.

Is that what you see?

This happens in Thunderbird 31.1.0 when your mailing list description includes several words separated by spaces.

Although not ideal, these workarounds should let you use your mailing lists until a proper fix is implemented:

  • While composing an email open the address book and select the list you are trying to send to, highlight all the names in the list and drag them to the To: box. This uses your existing data without modifying it.
  • Replacing the blanks " " between the words in such lists' descriptions with an underscore "_". This requires modifying your mailing list(s) description(s).
  • Downgrade to a previous version and disable automatic updates (Windows)

Thanks, Fabian. Eliminating the spaces worked like a charm! Bob
