[Dovecot] OS X Server Partition Problems

[Bryan Harrison]

I'm a nube to Dovecot and this list.  Please be kind.  ;)

I'm running Dovecot 1.1.20 and Postfix 2.5.5 on OS X Server 10.6.6.  

I've moved accounts from another, older cyrus-based server (thank god), and used fetchmail to imap the existing mail to the new server.  At some point, I developed a problem with my partition map being semi-ignored.  Mail is stored in multiple places, and I'm not sure why or entirely clear how it ended up there.  My log is overflowing with entries such as…

Jan 10 15:44:57 gilded-bat dovecot[65]: auth(default): od(john_doe_com): unable to find partition for tag=johndoe: using default mail location: /var/spool/imap/dovecot/mail

…referring to each of my defined partitions.

Here's what I semi-understand.

/etc/dovecot/partition_map.conf.default contains:

default:/var/spool/imap/dovecot/mail

/etc/dovecot/partition_map.conf contains correct entries like

default:/Mail
JohnDoe:/Groups/JohnDoe/Mail
[etc.]

dovecotd -n is below.  It's configuration with regard to mail store locations look ok to me, but then I'm a virgin.

In practice, mail is being stored in three different locations.  They're all full of mail directories and are busy.

/var/spool/imap/dovecot/mail
/Mail
/Groups/JohnDoe/Mail

…with of course the third entry being many entries for each client.  The directories described definitely exist.  Clients started out being able to see old mail that was transferred from the retired server, but no longer do.  I'm not actually clear which of the three mail stores in use are being accessed by whom or for what.  (And let's not even ask why none of this showed up in testing.)

In short, I'm over my head and the villagers are outside with the usual pitchforks and torches.  

Thanks,
Bryan
