Sorry, I will provide more detail =)

'server', lets call it MX, is sitting on a static address connected to  
the internets via a company that is unrelated to either A or B domains.

MX sends mail directly to recipient mail server, it doesn't use any  
intermediate upstream relay. Any mail it sends out has the envelope  
changed to domain A but it does NOT act as a relay for incoming mail  
to domain A, that is provided by webcentral.

Mail via Optus to A (webcentral) = Fine.
Mail via MX to A (webcentral) = Not received.
Mail via MX to B (optus) = Fine.
