How about :

Change the port forwarding on site A to send SMTP traffic to the
server at site B.

Configure the server to use Site A router for it''s external gateway ?
If there isn''t too much traffic then just do it for the whole server,
otherwise use policy routing to send just SMTP traffic via site A.


Also, how dynamic is the address at site B ? If the address only
changes infrequently, and this is a temporary setup, then could you
get away with setting a short TTL on the MX record and changing it as
required ? Or even use one of the dynamic-ip-to-dns services for the
hostname in the MX record.



Or, setup a temporary mail server at site A, with the same config
(user accounts etc) as the main server, but forwarding all received
messages to the other server.
