dovecot - Jul 2007 - How to stop POP clients from downloading mail after directory corruption

Transferring my email from a Courier server, as well as some
corruption in my dovecot installation caused all POP mails to be
downloaded again.

I surmised that the dovecot-uidlist file was not present in the first
instance, and was probably out of sync in the second.

Is there a way to do some reindexing and uid-list regeneration that
can stop the problem from occurring?

I don't believe that the missing uid-list file is the cause, as it is 
used for IMAP only. POP3 UIDs are dynamic, I think.

Check if you use the same POP UID format for both servers, e.g. (don't 
use quotes for name or password):

telnet oldserver pop3
user XYZ
pass ABC
uidl

telnet dovecot pop3
user XYZ
pass ABC
uidl


Then compare the output of both lists. It gave me the kick to choose the 
correct setting for the pop3_uidl_format setting.
