SMTP server name

OK, that I can do. Just give them the two addresses and the site name for each pair?

Would that change how e-mail is being sent though? If the PTR records weren't there, I would think e-mail would still be sent through the IPs I want, but would be returned as the receiving server couldn't verify "who" the sending server is.
 
Just ask them to add a PTR record for ip X.X.X.X facing something.mail.com

when you traceroute the IP address the last line (with that ip address) should no longer give an error, and now show the domain you asked it to resolve to.

Cool...but back to the original question...

Is there a way I can setup a mailserver for the xyz domain and force users of that domain to use that server? Right now all mail goes through the server ip address. I'd like mail for xyz to go through xyz, not the server ip. How can I make that happen?
 
The easiest way would probably be to setup the domain as an IP based site, using the IP you want to use as the mail server.

Ahh, ok...so now the next question, can I run multiple instances of sendmail? I'd like to have a mail server for xyz.com and one for abc.com.
 
I guess I need to do a manual config of sendmail/exim then? Or is DA supposed to be setting things up how I described automatically and it isn't so I should open a ticket?
 
You can use multiple IPs for your mailserver and only run 1 instance of exim. All IP addresses are basically aliases and aslong as the records are setup correctly you will be fine :)
