I have an Internal SMTP mail server that scans incoming and outgoing e-mails for spam and virus.
For incoming e-mails:
BM3.6 needs to hand it off to the SMTP device.
The SMTP device needs to hand it off to GWIA.
Outgonig e-mail:
GWIA hands it off to the SMTP device.
The SMTP device then sends it on to the internet.

I created 4 rule based on TID 10013822.
Rule 3 thru 6.
E-mails sent to the internet work fine.
E-mails are not recieved from the internet.
Apparently incoming mail connections are timing out at the BM server.

BorderManager and GWIA both reside on the same server.
The server has a PUBLIC and a PRIVATE NIC.

Thanks
Earl
