courier-imap/maildir/maildirquota.c
-----------------------------------
if (newquota)
{
parsequotastr(newquota, &info->quota);
if (info->quota.nbytes == 0 &&
info->quota.nmessages == 0)
{
close(info->fd);
info->fd= -1;
errno=EINVAL;
return (-1);
}
... and later ...
if ( maildir_openquotafile(info, maildir))
info->fd= -1;
if (newquota != NULL)
{
parsequotastr(newquota, &mq);
if ((mq.nbytes > 0 || mq.nmessages > 0) &&
(info->fd < 0 || info->quota.nbytes != mq.nbytes ||
info->quota.nmessages != mq.nmessages))
{
if (info->fd < 0)
{
maildir_quota_set(maildir, newquota);
if (maildir_openquotafile(info, maildir))
info->fd= -1;
}
else
{
info->quota=mq;
info->recalculation_needed=1;
}
}
}
if (info->fd < 0)
return (0); /* No quota set on this maildir */
Now, parsequotastr() returns nbytes=0 and nmessages=0 if it is unable to
parse the quota string, and should also log a warning along the lines of
quota string 'X' not parseable
But the above code shows that a new quota will not be installed unless
nbytes>0 or nmessages>0
So as far as I can see, it's not possible to remove a quota simply by
changing the LDAP attribute. You need to remove the LDAP attribute, *and*
delete the maildirsize file.
Alternatively, set a huge quota, such as "1000000C" (which means one million
messages, and no limit on the total number of bytes). However courier-imap,
plus whatever you're using to deliver into the maildir, will still go
through the overhead of calculating the quota for each message.
HTH,
