I've had a hell of a time getting major email servers to accept our email without considering it spam...  Part of my problem seems to be with PTR/RDNS and SPF.  I have those records set up for the IP address I have bound SMTP to in Xeams, but after getting many messages about SPF lookup failures I started taking a closer look.

Despite having Xeams SMTP bound to a specific IP, the email servers on the other end are getting OTHER IP addresses assigned to the same machine.  In the mail header, there are TWO "Received" IP addresses listed, neither of which are the IP I have SMTP bound to!

In other words, say I have 3 IP addresses on the email server:  5.5.5.1, 5.5.5.2, 5.5.5.3

I have SMTP Bound to IP 5.5.5.2 in Xeams, but servers are listing emails as being received from 5.5.5.1 and 5.5.5.3

Is there any way to make all traffic and header information come from a SPECIFIC IP?  Or am I missing something?...  Confused and dazed...
