[Dovecot] qpopper UIDLs and migrating to dovecot/maildir

[grant beattie]

hi all,

I am hoping to convert a 350K user qpopper installation using mbox to
dovecot and maildir (pop3 only).

many of the users "leave mail on server", and qpopper's UIDL format
isn't (yet) supported by dovecot. since the UIDLs have been written by
qpoppper to the existing mbox files (and will be preserved when the
mboxes are converted to maildir) it would be possible to do this
seamlessly if dovecot could read the UIDLs from the messages and
populate the index files as needed.

is anything like this already possible? it doesn't matter what UIDLs
new messages get, since they would never have been downloaded by the
user via qpopper.

any ideas would be appreciated.

grant.
