[Mimedefang] Where is my "quota exceeded" message?

[Roberto Machado]

Hi, All!

I'm trying to implement disk quotas in my system, and I'm having a few 
difficulties:

1) first I configured quotas in my filesystem, and I'm  using 
procmail, so everything should be straightforward. And actually works, 
but when I get bounces, sendmail returns simply:

    ----- The following addresses had permanent fatal errors -----
<user at domain.com>
     (reason: Can't create output)

    ----- Transcript of session follows -----
550 5.0.0 <user at domain.com>... Can't create output

The "quota exceeded" is apparently default, but I can't see it in my 
system. Now, the reason for my post: could Mimedefang be interfering 
with it? Procmail, when ran manually, gives me the correct output:

cat user | /usr/local/procmail/bin/procmail -Y -d user

/var: write failed, user disk limit reached

2) Particularly, I would like to implement quotas solely within 
Mimedefang, but from what I rad, Mimedefang won't allow me to do it 
ellegantly. filter_recipient passes the first envelope recipient and 
rejects the whole message, while MILTER provides the proper hook to 
simply reject a single "rcpt to". It is true that I am a few versions 
behind on Mimedefang. Has it been changed? You folks have some idea on 
how to implement quotas through Mimedefang, doing the right thing 
(i.e,, rejecting the bad recipient in the smtp recipient envelope 
message)?

Best regards,

Roberto
