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.
