[Dovecot] problems with debian 5.0 and thunderbird

Hi,

Does anyone have a setup guide for Thunderbird and Dovecot on Debian please?

Dovecot is 1.0.15

I have Dovecot running listening on 143 and I can telnet from the XP guest but Thunderbird cant or wont talk to it.

I have taken the # off listen and I get a telnet reply, no firewall is configured....

Ive set thunderbird up lots so I suspect its not Thunderbird but a dovecot config I have wrong.

regards
