Thanks Jeremy.

I feared that may be the case and it's likely to break some of the logic
going on in the RCPT_TO acl. My understanding is the router runs after
the ACL so any of my 'per recipient' settings may break.

I agree, but pesky customers ask for this feature and the majority of
MTA's/Servers willingly offer it - so it's hard to say 'no, I can't
offer you that'

It looks like the rewrite section, which runs before the 'rcpt to' ACL
(???) is my best (read easiest) option without too much carnage. I'll
make it my project for next week when I can think straight :-)
