Single Exchange 2007 Server environment. DNS records in place.
I want to change the FQDN exchange gives when it's sending mail from different domains.
For example if a user has two domains he's sending out as, (email@example.com and firstname.lastname@example.org), configured through exchange, i want the ehlo to read "mailserver.bob.com" when he sends out as "email@example.com" but when he sends out as "firstname.lastname@example.org" i want the FQDN given by exchange to read "mailserver.joe.com".
I was thinking of doing this through different send connectors, but the Send Connectors and their respective FQDNs are chosen by the receipt's address, not the sending address.
