Cant get Thunderbird to Authenticate

Hey Guys,

i followed on of linodes tutorials before to set up dovecot/postfix/mysql and after alot of screwing up i got it to finally work but there was a problem with the SSL certs, it would always say it was from another site so today i thought i would try it again to see if i had screwed something up.

So Today i reinstalled ubuntu 10.10 and followed the tutorial as best i could and everything seems to work great but i cant seem to log in from thunderbird at all bellow are my results

root@phoenix:/etc/postfix# telnet localhost pop3


Connected to localhost.

Escape character is '^]'.

+OK Dovecot ready.

Connected to localhost.

Escape character is '^]'.

220 ESMTP Postfix (Ubuntu)

ehlo localhost


250-SIZE 30720000








250 DSN

but everytime i try to log in i get this

Dec 7 14:38:09 phoenix dovecot: imap-login: Disconnected (auth failed, 2 attempts): user=

any help would be great!

i just realized i also can't send email from my googlemail to the server, it bounces back

Please post excerpts from your /var/log/mail.log from when you try and login.

thanks for your reply, i scrapped the server and reinstalled everything following the tutorial again and its working but im back to my original problem where Thunderbird is saying that the certificate is not valid :(

If you are using the default dovecot cert or another self signed cert, then you can just tell thunderbird to store that cert and it won't warn you again. Just click the box to permanently store the exception, and click the button to confirm the security exception.

If you are hosting for others and don't want them to see errors, then you would need an actual ssl cert.

that's my problem it works great but i am going to be hosting for others and i don't want them to see it :P.

are the certs expensive? also is it alot less secure not using ssl?
