Problems sending email from Thunderbird

I had a computer crash a few weeks ago and had to rebuild the software.  Moved up to Thunderbird 3.1for my email.  When I tried to receive email for my att account I had no trouble.  However now when I try to send from Thunderbird I get the following message;

Problems sending email from Thunderbird

An error occurred while sending mail. The mail server responded:  From address not verified – see  Please verify that your email address is correct in your Mail preferences and try again.


Before with an older version of thunderbird I had no problems.  I noticed now the one setting on TB is for “SSL/TLS”, not

just “SSL” or “TLS” as before.


I think you may have two problems.

If you are trying to send email using a “From” address other than your primary DSL email, you need to verify it through AT&T Yahoo’s complicated and confusing verification system.  See this support article: good luck to you in figuring out how to do it — I’ve done it for many accounts and still do it wrong several times before I get it right).
