Yep, the PTR records are fine, the problem is that the HELO responses
*don't* match the rDNS records.

Ah, brilliant! That worked *perfectly* - just what I was after!

The machine is a sort of a mailhub, so I know all mail for a certain
domain will be sent to a single smarthost. This smarthost is connected
via a different subnet, so I know the OS will always pick a certain
interface when connecting to it. I've set the "helo_data" to the rDNS
name of that interface and it all works perfectly now!

Many thanks for your quick response!

Cheers,
Adam.
