First, you should upgrade from 2006j to 2007a immediately. 2006j was an
intermediate version.
The only temporary files are small (a few bytes) files on /tmp used to aid
in locking.
Assuming that you are using the traditional UNIX mailbox format, note that
imap-2006 implemented UIDPLUS functionality, and as a result requires the
immediate assignment of UIDs to the message metadata in new messages.
That probably accounts for the difference; it needs to update in the new
messages at select time, rather than a lazy update that is deferred until
the user deletes and expunges messages.
I strongly urge that you not have hard quotas set so close to the soft
quotas. Hard quotas are bad juju, especially in the traditional UNIX
mailbox format which can actually *increase* in size as a result of being
opened due to the need to insert message metadata.
You should, however, have some policy mechanism to put teeth into the soft
quotas. At some point, I will make a public distribution of how UW does
internal quota enforcement as sample code. Briefly, UW allows a user to
exceed soft quota for up to 7 days or a threshold (which is still much
less than any hard limit); if either is exceeded then mail delivery is
shut off until the user gets below the soft quota. It's not impossible,
but it requires considerable talent and effort to reach the hard quota.

I run two FreeBSD mail servers (one 6.1 the other 6.3). The 6.1 server is
running imap-uw-2004g while the 6.3 server is running imap-uw-2006j (both
compiled from the ports tree with the same options to check mail in /home
instead of /var/mail). Both servers are using soft and hard filesystem
quotas. Clients are connecting with squirrelmail web mail client on a
third server.
The problem I am experiencing is that when a user who's mail is stored on
the server running imap-uw-2006j and they are close to their hard quota
the get the following message reported by squirrelmail:
ERROR : Could not complete request.
Query: SELECT "INBOX"
Reason Given: Unable to extend mailbox: Disc quota exceeded
The last line being what is returned by uw-imap. The user's quota usage
looks like this on the file system:
[EMAIL PROTECTED] /home/r]# quota -u rhetoric
Disk quotas for user rhetoric (uid 23788):
Filesystem usage quota limit grace files quota limit
grace
/home 12284* 10240 12288 7days 10 0 0
This is a problem because users cannot see their list of messages to be
able to delete them. Interestingly enough, if I rsync the user's home
folder over to the 6.1 server running imap-uw-2004g and check that account
with squirrel mail I can see the list of the user's messages just fine.
Filesystem quota information is identical to that which I pasted above
from the 6.3 box.
Has anything changed between the 2004 and 2006 implementations of uw-imap
that would cause this? I'm unable to find a changelog. Any help would be
appreciated.
Thanks in advance!
