dovecot - Apr 2012 - Courier to Dovecot migration script issue

Hi!
Forgive my bad English.

I trying to migrate to Dovecot 2.0.18 from Courier 4.10. 
I using a script 'courier-dovecot-migrate.pl' from oficial wiki - it
works without errors and creating dovecot-uidlist, etc. .

I running Dovecot on a different port: 11149.
When I connecting to port 11149 from Thunderbird, all my message headers are
reloading.

Please help me to solve this issue.

Best regards,

Victor

telnet localhost 143
a login user pass
b select inbox
c status inbox (uidvalidity)
d fetch 1:* uid

telnet localhost 11149
a login user pass
b select inbox
c status inbox (uidvalidity)
d fetch 1:* uid

Check if the "c" and "d" outputs are the same for both
servers. If they are, then the migration was successful and the problem is
something else, such as maybe the client always redownloading messages because
you changed the port (or something else).
