[courier-users] Advice and patch about 'cc' followed by 'to' in .mailfiler

[Alain NAKACHE]

Greetings All,
In maildropex man page I can read the following example : 

if (/^From: [EMAIL PROTECTED]/ \ 
    && /^Subject:.*[:wbreak:]project
status[:wbreak:]/) 
{ 
    cc "!john" 
    to Mail/project 
} 
But in case of the 'to' temporary failure (Over quota for example)
john will receive several times the same message until the message is
successfully delivered or canceled which can be a problem.
I tried to simulate a better behaviour using an 'exception' command
similar to this : 

if (/^From: [EMAIL PROTECTED]/) 
{ 
OK=0 
exception { 
                cc
"$DEFAULT/.domain" 
                OK=1 
                } 
} 
echo 'EXITCODE=$EXITCODE' 
if ($OK == 1) 
{ 
                to
"!john" 
} 
else 
{ 
                exit 
} 
But in case of failure, the result is : 

maildrop: maildir over quota. 
EXITCODE= 
and maildrop exits whith a null status. If I suppress the 'else' in
the above mailfilter script, the message is delivered in the $DEFAULT
maildir too (as expected ?).
By applying the following patch :

I manage to obtain a good behaviour (which is valid only in the case
of maildir deliver)
Did I miss something ?
