[maildropl] maildrop bouncesaying

[Arthur K. <ar...@bl...>]

Hi,

My system:
qmail 1.03
maildrop 2.2.0
vpopmail 5.5.0 with vusaged
courier-imap 4.7.0

I am using /etc/maildroprc to filter messages and handle the quota 
system. When the quota limit is reached, maildrop stops delivery and 
should send a bounce to the sender. This is the part of my script which 
supposed to handle this behaviour:

exception {
                 xfilter "/usr/local/courier-imap/bin/deliverquota -w 90 
$VHOME/Maildir"
         }

         if( $RETURNCODE == 77)
         {
                 to "| /var/qmail/bin/bouncesaying '$EXT@$HOST is over 
quota'"
         }
}

.qmail for all users is:
|/usr/local/bin/maildrop

Messages are indeed stopped from delivery but no bounce is sent. The log 
shows this errors:
!Err: |/var/qmail/bin/bouncesaying '[email] is over quota'

and the qmail log:
deferral: 
[email]_is_over_quota/maildrop:_error_writing_to_mailbox.//usr/local/bin/maildrop:_Unable_to_deliver_to_mailbox./

Also, no quota warn message is sent to the user.

What I'm trying to accomplish is a quota and filtering system for my 
mail server. I have here 2 options:
1. Solving the problem above
2. Without maildrop, vpopmail is handling very well the bounces but I 
lack the filtering functions. Is there a way to check first for quota 
(user and domain) using vpopmail and afterwards send the message to 
maildrop for filtering?

Thanks for the help,
Arthur
