dovecot -n output would have helped. Anyway, some POP3 clients become confused 
if there are duplicate UIDLs. Recent v2.1 versions have a pop3_uidl_duplicates 
setting to avoid those.

[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.
