- BCWareNoSpam listening on port 25 which does blocklist DNS lookups,
- McAfee Webshield SMTP listening on port 8125 which virus scans the inbound and outbound SMTP traffic and
- Eudora Worldmail 2.0 listening on port 2225 which is the message store.
So the mail path looks like this
(25) BCWare -> (8125) Webshield SMTP -> (2225) Worldmail.
Buying IMail will make the BCWareNoSpam product redundant so it will be removed from the system however since we already have the license for Webshield SMTP I'd like to still use that for virus scanning the SMTP traffic before it gets to the message store.
This leaves me with a problem, if I set Webshield to listen on port 25 and pass on mail that's found to be clean then the DNS Blackhole feature of IMail will become disabled because all mail will be seen to be coming from the internal servers IP address (Webshield SMTP adds its own Received header).
Is there a way to have IMail ignore received headers from the localhost address and look back at the previous received header to see where it came from before it hit the localhost? Or can you think of any other configuration that would allow WebShield SMTP to interact with the IMail server so that IMail answers the door (so to speak) on port 25 passes the SMTP traffic off to WebShield which then passes it back to the IMail message store on another port?
Thanks for your help in advance on this.
