Hello Stewart,

You have to previously know or have determined: a) what FS's are under quota

That's easy in my case, because each filesystem is listed in dovecot.conf:

quota = fs:"Spool":mount=/var/spool/mail quota2 = fs:"Home0":mount=/home/f0 quota3 = fs:"Home1":mount=/home/f1 quota4 = fs:"Home2":mount=/home/f2 quota5 = fs:"Home3":mount=/home/f3 ...

AND b) know which ones the user uses

That should be easy to, because they are listed in mail_location. In my case this is: mail_location = mbox:~/Mail:INBOX=/var/spool/mail/%n

AND c) then make multiple calls, one for each FS that the user has stuff in

Let take 'quota_transaction_set_limits' as example:

If I understand Timo's source code correctly this is done by looping through the mountpoints of all quota roots. But then, and this is a problem, the lowest quota limit is used, because it is not checked, if the mbox file acctually _resides_ in this filesystem.

Well... I think what this behavior could be "fixed" in the same way I've used for GETQUOTAROOT:

I've just implemented a callback function 'root_match_box' that returns 'true', if a Mailbox resides on the filesystem defined "mount=" in quota definition and 'false' if not. This optional function is used in 'quota_root_iter_next' to filter the list of all quota roots.

From the source code: ----------------------8<---------------------------------------------- roots = array_get(&iter->quota->roots, &count); if (iter->i >= count) return NULL;

for (; iter->i < count; iter->i++) {

if (roots[iter->i]->backend.v.root_match_box != NULL) {

  if (!roots[iter->i]->backend.v.root_match_box(roots[iter->i],
          iter->box))
    continue;
}
...

} ---------------------->8----------------------------------------------

The same should be correct in quota_transaction_set_limits, quota_transaction_commit and quota_default_test_alloc

But I should have a deeper look at this... :-)

BTW: If this behavior is indeed AIX specific, that's no problem, In this case the function should always returning 'true' or just not be included in the list of callback functions.

Regards, Ralf
