What about using relay_domains and relay_recipient_maps. I am using this

Hi all,
I have a Postfix/MailScanner front-end set up which works well, however
I'm not sure I've configured it correctly (or in the best way)...
The box uses header_checks to place all incoming messages in the hold
queue (standard stuff) and transport_maps define which mail server the

Hi,
Just a quick config question, which I'm not too sure how to achieve.
I'd like to enable recipient domain validation, which I've partly done (at
the data stage), however if you then enter another "rcpt to" after the
data command failed, it'll allow it through. E.g.
