There appears to be some obfuscation there... do you *actually* mean you have
the two boxes set with 'hostnames' or with 'HELO' as

...'ourwindowsbox'... '...ourlinuxbox...'    or something else..


Aside from the two IP's listed, are there other IP or <domain>.<tld>:

- will the servers be in a pool, use other IP, relay from other IP?

- do they need to selectively 'HELO' depending on sender or choice of 'interface'?

- do you need to support forms or other web-driven mailing tools?

With mailing list management software, yes, 'tick a box' easily.

With Exim, less so, as, strictly speaking it not always 'legal' in all
jurisdictions (may fall under concealing the source, etc.)

'Campaign software' does not compute...

It would perhaps make more sense to a Mailing List Management toolset user group.

Should not be hard once you get the basics sorted. You aren't there yet.
