Hi,

I would like to try and achieve the following behaviour:

Case A
=====
Message sent to us...@hosta.xxx.yyy.zzz
hosta.xxx.yyy.zzz contains an MX=0 record in our DNS
Result: message to be routed to this user on this host

Case B
=====
Message sent to us...@hostb.xxx.yyy.zzz
hostb.xxx.yyy.zzz has no MX record
Result: message to be delivered locally to user2 (and an alias is then used to 
deliver the mail to the user's mailbox)

I have tried putting:

.xxx.yyy.zzz    local:

in the transport map, but this also tries to deliver locally in CaseA.

I know I can put:

hosta.xxx.yyy.zzz       smtp:[hosta.xxx.yyy.zzz]

in the transport map, but there are 100's of hosts that would then need to be 
entered, and I would rather not have to rely on maintaining this list.

Any thoughts, or is this not possible?

Robin
