"451 Nameserver timeout during parsing" I expect

RFC readers will know that this behaviour is wrong :( but regulars will
know that MMDF is not the best MTA ever :(. That said, this should not
be happening - some logs of the failures would be useful. The best place
to send details of_this_particular_fault! would be postmaster@demon.net.

I am reliably informed that it will be nothing to do with the anti-spam

interest (if you can produce the logs - see above).

You could also join the "testers" group, which would then allow you to
use post.eng.mail.net, which runs a different MTA which could give you
less problems -- different reporting arrangements exist for problems
there, which is why joining the official group is important.
