No.  That is not the way mail servers work.

That is because MailScanner runs two SMTP processes - one accepts mail from 
the source (sender), and the other one sends mail to the destination 

That second process can only use the IP address of the mail server, becaue it 
has to communicate with the destination mail server, which therefore needs to 
send its replies back to the MailScanner machine's IP address.

This is no different from using a mail server without MailScanner running on 
it; in that case the recipients will see the IP address of the mail server as 
the origin, and the IP address of the client as the previous hop in the path.

I don't understand this question.



My life is going completely according to plan.

I do sometimes wish it had been *my* plan, though.
