IMAP: missing old mail

["Jochen Küpper" <jochen@jochen-kuepper.de>]

Dear All,

my imap server was changed under the hood and now I am "missing" my
old emails.

The situation is as follows: Our imap server was upgraded to a new
machine and new software (now: Cyrus IMAP4 v2.1.11 server). The old
and the new server both were/are named imap.somedomain. All mail was
copied from the old server to the new one.

If my sysadmin looks at my mailboxes with mailx all my old mails seem
to be there, however in Gnus only new messages -- arrived after the
server change -- are visible.

I have tried to kill and resubscribe mailboxes, I have (for a few
mailboxes) deleted all entries in .newsrc.eld and resubscribed, but
still the old messages cannot be displayed. (Btw: Yes, I do C-u RET to
enter the group.)

What needs to be done to let Gnus find the old messages, too?

This is using Oort Gnus v0.16, but I had the same behavior with 5.9.

Greetings,
Jochen
