So I take it that's a no the... ;-)

The current system of forwards works, but the product that does the 
translation of the outbound is being discontinued so we need to find 
another way of doing that.

I thought it would be a simple change to the outgoing address, but if not 
time for some sendmail/procmail jiggery pokery...

Cheers

You can certainly put aliases for all standard list-related addresses (8 
per list) on your
main mail server, but how will the main mail server handle an inbound 
delivery error
message resulting from a passive probe?

When LISTSERV sends a passive probe, the recipient (subscriber) address is 
encoded in the
left-hand side of the envelope-sender address on the probe. If the probe 
is undeliverable,
the inbound delivery error message will have the original recipient 
(subscriber) address
encoded in the left-hand side of the envelope-recipient address. This 
technique ensures
that LISTSERV can determine the original recipient (subscriber) address on 
the
undeliverable probe, even if the probe was redirected to a different 
address before it
bounced. There are a multitude of reasons why this can happen.

As I see it, there are two ways to deal with this issue:

* Create a new list-specific probe-style alias on the main mail server 
every time someone
subscribes (or is added) to a list on your server, and every time an 
existing subscriber's
address is updated by the subscriber, the list owner, or the site 
administrator. In
addition to the 8 standard aliases for each list, you will need a seperate 
alias for every
subscriber on every list. You will also need a process that removes 
individual aliases
when they are no longer needed.

* Continue to use host-specific addressing and let the mail server 
software on the list
server handle the resolution of the left-hand side of the envelope 
recipient address. This
will not require any new aliases on the main mail servers.
