Greetings,
  I have a single server with multiple IPs on the same ethernet interface.
 I want postfix to listen to all of them but say it's name differently.

As in:

.100 = mail.domaina.com
.101 = mail.domainb.com
.102 = mail.domainc.com

I have reverse DNS setup for this but now I want Postfix to say:
  220 mail.domaina.com ESMTP Postfix
when someone conencts to .100 and to say:
  220 mail.domainb.com ESMTP Postfix
when someone connects to .101.

Also when Postfix is sending I'd like it to use the domain of the sender
to determine which interface and name to use for sending.

 I've been having trouble finding and answer in the help and with Google.
All my multiple domain searches show how to accept for multiple virtual
domains, which I've got. Ideas? What should I be searching for?
