[Dovecot] dovecot mbox to dovecot maildir migration
Hi,
I'm migrating accounts from one server with dovecot mbox and pam nss-ldap authentication to a new server with dovecot maildir and mysql auth (no posix accounts).
My problem is the pop3 uidl format on the two servers are different, even though I'm using pop3_uidl_format = %08Xu%08Xv in both configs, I'm always re-downloading left messages on my test runs. Is there a way I could reuse the X-UID and X-IMAPbase headers on the converted mails. Issuing the UIDL command via pop3 always give a different result for the mbox and maildir spools.
The X-UID and X-IMAPbase headers are present in the converted mails. The first number of X-IMAPbase maps to the mail UIDVALIDITY and the second is the same as X-UID, the mail uid.
Thanks.

You'll have to make your conversion script create dovecot-uidlist file based on the X-IMAPbase and X-UID headers. There could be existing scripts to do that, but I'm not sure.
I've already hacked into the mb2md script and creating this file. I think its dovecot index related, but I don't know how to write this file.
