[Dovecot] UIDVALIDITY Change

Hi,

I'm attempting to migrate a Courier-IMAP Server to Dovecto. I've followed the instructions in the Dovecot wiki and converted the indices using the provided perl script.

Howevery I'm getting "UIDVALIDITY changed ..." messages in the logfile and some of the test clients list some messages twice. I didn't find much about this issue in the wiki.

Any hints?
