[exim] Message replication

Hi

As noone seems to know how to fix my message sharing scheme, I think I need
to find another way.

So my question put simple:


How can I send one mail to many servers (changing as few as possible) ?


My last resort would be to send that mail as attachment so some new mails to
special addresses at the different hosts and then use a pipe transport to
deliver it to a script that unpacks the attachment and reposts the mail to
exim again. However this seems fairly much overhead for something that is
build in to exim already.

Any hints are welcome.
However I only have 'bout 13 hours left...


Regards,
Steffen
