Assuming that Declude JunkMail is running on the existing IMail server (and
not the Smarthost), there isn't anything special you would need to do.
If you were adding a gateway for incoming mail, you would need to let
Declude JunkMail know about the gateway (using an IPBYPASS line), as it
would alter the IP address that connects to IMail. But for outgoing mail,
you don't have to do anything for Declude JunkMail.

That's not a problem. Although some mailservers will check your reverse
DNS entry, about 90% will just verify that it exists, with the other 10%
making sure that it is a valid hostname. But only about 1 in 1,000 will
actually make any attempt to determine whether the reverse DNS entry
matches anything (since it's not possible to do that accurately).
