Re: Migrate Dovecot 2.0.16 (mbox) to Dovecot 2.3.16 (MaiDir) and preserve POP UIDs

From: "Barbara M." <barbara@rfx.it>

I am obviouly interested to resync the INBOX with somethig that give to clients the old UIDs so they don't re-download all messages in the inbox as duplicates into their mailbox.

When I mitigated away from qpopper, I configured

protocol pop3 {
...
pop3_reuse_xuidl = yes
}

Maybe that's of use to you?
