A gold star for Chris and many thanks!

Yes, it would appear that the Vista client is differently broken with
respect to multi-line messages. Outlook only displays the last line, Vista's
Microsoft Mail client just ignores them. A "control =
no_multiline_responses" applied to local hosts early in the ACLs and all is
well.

That actually works better for our MUAs anyway, as the first 70-odd
characters of the message are far more useful for reporting failures than
the last line (which tends to end up being "550-if you believe this to be in
error").

Many thanks for all the suggestions,

Adam
