Well, I've now removed courier-imap and installed cyrus instead, to do
some testing. It works so far that I can send mails to my testuser on
the server, the testuser can read them via IMAP, and he can create and
delete folders. My first impression is that cyrus is considerably
faster than courier.
But to get a decent number of mails into the testusers mailbox for
testing, I'd like to copy over all mail from
~test/Maildir/.debian-users into
/var/spool/cyrus/mail/user/test/example (or another folder,
preferably debian-users). Then, I'd run reconstruct -r user.test
and reconstruct -m, and my test should be able to merely read all
those mails.
Before copying over about 38000 files, I just copied over one single
file from ~test/Maildir/.debian-users/cur to
/var/spool/cyrus/mail/user/test. After that, I've run reconstruct
as above, but the message does *not* appear in the INBOX when viewed
via IMAP. Ok, I renamed the message file to 1. and did reconstruct
again, but it still doesn't appear in the INBOX.
Finally, I removed the cyrus.* files from
/var/spool/cyrus/mail/user/test and did a reconstruct again, but
to no avail. Even worse, the cyrus.* files are not recreated, and the
mailbox has become completely unavailable via IMAP.
Here's some output I get:

When trying to connect via IMAP, I'm getting the message that the
mailbox doesn't exit. Recovering from crashes/errors doesn't seem to
be so easy. What am I doing wrong here? Are there other programs to
recover from problems?
