Hi List,
to start with, it's not a vital problem, I only want to fix sth
annoying me.
As quite a number among you, I'm running a LAN connected to
the big world via switched ADSL.
I'm looking for a MTA that is capable of rewriting addresses
*only* on mails that leave the LAN.
In general I'm using postfix as MTA of choice, using generic_map for
address rewriting, but that fires whenever a message leaves the host,
hence I see external addresses even on internal mails.
With postfix a solution would be to run a second instance with it's
own queue for dispatching, passing only outbound messages to the
address rewriting instance.
Here's the question again: which one of the abundance of MTAs in
Debian is capable of address rewriting depending on destination?
