E-mail worked until the update. Sending of message failed. An error occurred sending mail: Unable to authenticate to SMTP server smtp-server.rochester.rr.com. It does not support authentication (SMTP-AUTH) but you have chosen to use authentication. Uncheck 'Use name and password' for that server or contact your service provider. Reproducible: Always Steps to Reproduce: 1.Tried to reply to email received. 2.Then tried to send test email got same error. 3. There should of been no error message like before the update.

My service provider went though a test with me and showed from their webmail site I receive and send mail, but cannot send or receive with Thunderbird. Something has changed in the update version 3.0. Test was done at 10:30 PM 12/13/2009

dup of bug 534111?

Smilee your issue is only with sending right ? can you read the bug wada is suggesting and see if the workaround solves your issue ?

(In reply to comment #3) > Smilee your issue is only with sending right ? can you read the bug wada is > suggesting and see if the workaround solves your issue ? I read through bug 534111 and this is not a campus computer. It is always used at home. I do not see where an update to a newer version needs to start changing parts in the setup when that was working fine in ver 2 whatever. I'm not a computer geek just an old senior citizen who liked using thunderbird until now.

(In reply to comment #4) > geek just an old senior citizen who liked using thunderbird until now. yes it's bug That the quality assurance team didn't see before the release.

(In reply to comment #4) > I read through bug 534111 and this is not a campus computer. Please read bug 534111 comment #0 and bug 534111 comment #1 only(that bug was morphed by relevant but different/important issue.) Or read bug 534551, please. Same problem as bug bug 534551.

My problem is the same. Can receive mail, but can't send since update.

> An error occurred sending mail: ... It does not support authentication > (SMTP-AUTH) but you have chosen to use authentication. This is a duplicate of bug 524868 (case #1), which was in turn resolved as a duplicate of bug 522633. The setting in question is in Tools/Edit > Account Settings > Outgoing Server (SMTP), then select the matching server and click Edit. Uncheck the "Use name and password" box to disable authentication. Also see bug 542065 to make this setting better discoverable.

I unchecked user name and password in outgoing server. outgoing mail still isn't working

That's because it's a different problem. Please stay in your own bug 564588.
