dovecot -n output would have been nice. Also do you see anything in
If you're using the default pop3_uidl_format it'll rely on IMAP UIDs to
stay the same, and I guess it's possible that due to some other problem
they change (that should be logged as an error/warning though).
You could try setting pop3_uidl_format=%f, but it will cause everyone to
redownload mails. With newer Dovecot versions you could set
pop3_save_uidl=yes and when you think everyone's downloaded mails once
you can safely change the pop3_uidl_format.
