Subject: [EXIM] rewite-rules
I want to use rewrite rules to change
addresses of certain hosts/domains , for which our exim will work
as mailrelay to route all emails to the given destination address.

I've to change the sender-address
from :

sample:

 loebner@??? ->
    margrit.loebner@???
over entries in special databases.


To write one rule to do this rewrite-operation... I think, this is
not difficult
(I had many aid from other german exim-admins to understand rewriting,...)

If it goes right, there is no problem, but I will reject the email, if
the rewrite rule can't find an entry in the database :

    only definded users from defined Hosts/domains can email over
    our exim-configuration
    -> user of host must be defined, if the host is defined in our
       configuration


What can I do?
::::::::::::::
I've an idea:
 If rewrite can't rewrite the sender I change the To-Fields in
 envelope/header to an fail-Address 
-> mail to a special fail-address -> over a filter-process I can detect
                     the given error (rejection)


???
