Hi all,
I'm migrating a Postfix + Dovecot 1.0 server with mboxes to Qmail + Dovecot 1.4 with Maildirs and encounter the following the problem.
Using perfect-maildir.pl from: http://perfectmaildir.home-dn.net/ i can relatively succesfully convert the mbox to a Maildir. The problem, however is that clients with "leave mail on server" set to on retrieve all email a 2nd time.
I understand this must be because the email client "sees" a different UIDL and downloads the message again. Looking at the 1.0 configuration, i do not see a "pop3_uidl_format" setting. So was wondering how the UIDL is generated.
Is anybody aware of a conversion script that properly maintains the UIDL? Or am I misisng something else here?
Hi,
Please look at http://wiki.dovecot.org/Migration/MailFormat
There's a modified version of mb2md.pl there that will keep the existing UIDL info.
As for "pop3_uidl_format", I seem to recall the source needing modification to change the format in earlier versions of Dovecot, until it was added as a configuration option.
OT: I'm curious as to why you're migrating from Postfix to Qmail.
Regards,
Jase.
