Bypass REDIRECT rule in header_checks for specific sender ?

[George Papas]

Happy new year everybody,

I have a filter in my header_checks file that redirects messages send to 
undisclosed recipients

to a mailbox to monitor and fw to intended users if of any value like 
this :

/(^To:\ undisclosed-recipients\:\;)|(To:\ undisclosed-recipients\:\ ;)/ 
REDIRECT s...@email.add


Unfortunately there are some valid recipients that use this technique to 
send messages and

I tried to bypass this by adding their address before the redirect rule 
with a FILTER action but discovered

(after reading the manual page ) that :

Note: this action overrides the*FILTER*  action, and  affects  all
               recipients  of  the  message. If multiple*REDIRECT*  actions 
fire,
               only the last one is executed.

Is there any other way to stop the check on the first hit ( the sender 
address) and not fire the

REDIRECT action ?


Thanks in advance for any info
