Virtual SMTP and outgoing IP

Hello!

I got dedicated server with 5 IPs.

The primary IP address bound to the external interface of the Mail Server is always used.

I need to bind a specific IP address.
This is an important issue because many benighted network admins will use reverse lookups on their SMTP servers as a very crude and ineffective method of spam control.

How to do it in IIS Virtual SMTP?
Could you please suggest a mail server (smtp/pop3) software to control outgoing ip?

Thank you.

 

This is unclear. It sounds like you already have a specific IP address bound to the NIC. Or do you want another address on the same card?

A firewall or filter will restrict traffic to specific addresses, if this is what you are trying to accomplish.

Can you be more specific?

22.22.22.5 = primary default ip. 22-22-22-5.server.dedicatedprovider.com
22.22.22.6 = domain1.com=mail.domain1.com
22.22.22.7 = domain2.com=mail.domain2.com
(ps: PTR does exists for all ips)

I need to bind a specific IP address.
For example: outgoing ip for @domain1.com mail must be 22.22.22.6 (not default 22.22.22.5).

 

Cannot be done

We've been searching for the answer to this question for literally a year. We've tried countless things and scoured the net for an answer. I'm close to simply saying it cannot be done. If you find an answer, I will pay you handsomely for the solution. Seriously...
