I am running RedHat Linux and Exim 4.52 on a box in my DMZ. It acts as
a spam/virus scanner and smart host relay for an Exchange box inside my
firewall. The Exchange users insist that their 'Out-of-Office'
autoreply messages need to be sent to external addresses as well as
internal. We haven't found a way to prevent Exchange from sending
'Out-of-Office' messages in reply to spam, so the smart host gets a lot
of Autoreplys addressed to invalid addresses. When it can't deliver
them it sends a bounce message back to the Exchange users, so for every
spam they also get a non-delivery notice for the 'Out-of-Office' message.
These 'Out-of-Office' messages are easily identifiable by their subject
line, and I would like to treat them similar to the way bounce messages
are treated: try to deliver them for a short period of time, and if they
are non-deliverable, just delete them. I know from experience that Exim
is incredibly flexible, but I haven't been able to figure out how to
make it do this. Any thoughts or pointers would be much appreciated.
Thanks.
Russ
