Magnus,

Thank oy for your reply, with your input, I think I've figured most of it
out. I do have a couple more questions below:

Since this is going to be a virtual mailbox domain rather than a virtual
alias, I think then I don't need to create an entry in virtual(5) correct?
One point I forgot to mention in my original e-mail is that even though the
recipients don't have mail boxes on the system, their domain name matches
the domain name of the SMTP server.

I understand how do add a virtual tranports in main.cf, how do I match that
transport to the domain name? Based on what I've read, I think I do it in
the transport(5) file. Is this correct?

Also, I'll still need to configure main.cf to know about this domain. Is
this correct?

Thank you so much for your help.

Regards,
Kevin
