Moving from sendmail to postfix

[Graham S. Jarvis]

Hello Thom,

That was it ! - I postmap'd the transport file but I thought transport_maps=  
was a default.

Many thanks - I know my question wasn't really for the mailscanner list, but I 
thought this was the best place to ask given what I'm trying to do.

I knew there'd be someone here who also likes to run the mail server on a 
physically different host than the web server.....

Thanks again!

-Graham-
