Re: [Dovecot] Help!
Hi, I have installed sendmail, dovecot, and squirrel mail. The squirrel mail portion of it works just fine, but I would like to have Mozilla Thunderbird as a client. Whenever I try and connect to the server it says Thunderbird failed to find the settings for your email account. We do have an MX record in DNS pointing to our server. We are using Ubuntu 12.0.4.1, and have Dovecot 2.2.6 sendmail version 8.14.4-2ubuntu2 We are doing this for a class project and it is due by Tuesday 10/16/2012.. I have found Thunderbird's automatic setting detection mechanism to be rather unreliable. Try entering the settings manually. I am one of the automx developers. Have a look at http://www.automx.org. It is open source. I also finished setting up a test server, so you can try with mail address aut...@automx.org, pw: automx and see how it works.

This backtrace is rather weird. Could you also do (instead of bt
full):
fr 1
p *ns
p *ns.user
p *auser
It crashes because auser-dict = NULL, but it should never be NULL.
Hi Timo,
this is a new backtrace:

[Dovecot] POP UIDL
Hi I run a small mail server with Dovecot and postfix. Several of the accounts are popped by an external email provide I use, mostly out habit and also for a bit of redundancy. I have no details on that external server except that it uses exim. Lately, it's been repopping mail from accounts (mail is left on the server so I can use IMAP) at fairly frequent, but undetermined, intervals. Before I take it to them, I want to be sure it's not an error on my side. How can I be sure Dovecot does not have a problem with the UIDL list causing this external server to repop the mail? For the record, I'm not inclined to think it's a Dovecot issue, but since that's the bit I can fix, I'd like to be sure. Cheers Simon
