Thank you Christian. "pop3_save_uidl = yes" setting resolved the problem.

Regards.

Hi,

I've very old Dovecot version so I'm trying to migrate new disk and current version of dovecot. But POP3 accounts have "version 1" .INBOX/dovecot-uidlist files so clients download the messages again.

How can achieve not to download to mailbox after copy to new disk? Is there any script or something to migrate index v1 to v3?

thanks for your suggestions.

Have you actually looked at the configuration file in question (20-pop3.conf)? Setting "pop3_uidl_format = %v.%u" should do the trick and if you're using maildir (we do) you can in addition set "pop3_save_uidl = yes" and in the future change to different UID format.
