Hi GordonYes it would be the "one acting as a switch to send the message to 2 servers downstream? " option, so what should i put in the /etc/mail/aliases file to make this work?
I have forward to groups, like sales in the past, but never forward all email to another before. I would have use the smart host option.

Or do you realy have 3 servers - one acting as a switch to send the message to 2 servers downstream?If you have 3, you could simply use the /etc/mail/aliases on the incoming server and send it to the 2 other servers - they'd at least get the same headers, but wouldn't be able to use any IP address based blacklisting unless the rules were really clever to scan all the headers and ignore the last sending server.Watch out for backscatter though.
