I want to be able to provide the following as a mail service, I've been doing it to date with two seperate servers but it would be great if ME was capable of doing this on a single install:
domain1.com [external address 100.100.100.20] > uses Antispam service > only allow delivery to email@example.com from 123.456.789.123, the antispam provider's outgoing IP.
domain2.com [external address 100.100.100.30]> don't need/want antispam > allow delivery for emails originating anywhere.
I can have the two services listing on differing external IPs on the firewall which resolve to the same LAN address - but I need to make domain1.com only be accessible from the antispam gateway - else naughty spammers could technically send to 100.100.100.20, to domain1.com
So basically, is MailEnable capable of filtering incoming IPs on a per POSTOFFICE/domain basis in any way?
Hope someone can help
