Folks,
Proceeding with my (sometimes steep) learning curve on Cyrus Murder (and
preparing a Wiki guide to same) I have recently experienced a case of
missing mailboxes.
Let me explain... I started out by splitting a long-running non-murder
2.4.10 host into a single frontend and backend, with a separate mupdate
master. I then added a second frontend -- no problem. I then added a
second backend (several problems, but a lot of learning!) and ultimately
moved an account onto it.
The next day, I tweaked some settings in the config files and restarted
the Cyrus server. Went to look at my mailboxes and they're gone! Uh-oh!!
Long story short, the original backend is configured with 'servername:
mailbox.example.com' and the new backend is 'servername:
mailbox.wi.example.com'. I had moved the account with this command (in
cyradm):
mail.example.com> xfermailbox user.onlight mailbox.wi
Problem is that ctl_mboxlist.c:do_dump() compares the mailboxes.db entry
for the mailbox with config_servername, and deletes any mailboxes on the
local host which don't match. The mailboxes.db entry contains whatever
string the user types in to cyradm's XFER command, regardless of what
the target server thinks its name is.
Now I can understand this, to some extent, but seeing as in several
other places Cyrus cavalierly discards portions of hostnames (i.e. all
the host_* settings in imapd.conf) it seems odd that here it behaves
like this. The user might enter quite a few different names into cyradm
and successfully transfer the mailbox, only to have it disappear upon
reboot/restart. They may use a short name (as I did) or an IP address,
or any other host name which resolves to the destination server, and the
command will succeed.
It seems to me that since servername is so important, this behavior
should at least be mentioned in the imapd.conf(5) manpage. But really,
I would expect that once the source server is connected to the target
server via IMAP protocol, if the target lists a servername in its
greeting or capability string (as it will unless 'serverinfo: off' is
set) then THAT name is what should be entered into the mailboxes.db
file, and not whatever shorthand the user may have used.
Is this doable?
Cheers,
-nic
