Specify Sendmail Outbound IP for E-mail Header


Summary: Our company is currently deploying a Sendmail server for mass marketing and member update e-mails for 9 different domains, while making best effort to comply with common SPAM filtering practices (i.e. valid opt in and/or out information, external MX, A, SPF, and PTR records, mail delivery retry intervals, etc&).

Question: How can I get the e-mail header to reflect the correct domain and public IP address that the mail is being sent from in the header?

Issue: External E-mail header reflects "Received: from localhost.localdomain (unknown [216.203.40.133])" regardless of the domain the mail originates from.

Configuration: I've configured 10 different virtual IP's on one NIC as well as configured Sendmail for the different MTA's. Each MTA session has been given a dedicated public and private IP and yet all e-mail headers reflect the public IP associated with the private. We're also using a PIX 506e for the firewall and created dedicated NAT objects for each domain.

Thanks in advance.
