Multiple domains on server sending from main IP - Help!

Hello everyone,

I have a server with multiple domains on it. Each domain has it's own
dedicated IP. When any user sends an email from any domain, they all
appear to be sent from the main IP of the server BUT I need it to
appear to come from each domain's dedicated IP

Is there a way to install or configure sendmail to do that?
Do I need to run a separate instance of sendmail for each domain or is
there a smarter way?
If I do need to run multiple instances of send mail, can I do that for
50 or 60 domains on the server?


Thanks for any advice you can give me.
Michael

Look in to the DaemonPortOptions "b" Modifier to cause outgoing email to
be bound from the incoming interface.

Also look in to the ClientPortOptions "h" Modifier to cause the client
to use the name of the interface that it is bound to as it's HELO / EHLO
name.

I guess theoretically, if you don't mind managing that many different
queues and config files, yes you can, but try what I have suggested
above first.
