Milter-greylist

Yes, the firewall is between the mail server and the internet and does 
port forwarding. Looks just like you've illustrated.

I did change my firewall. I had been using a Slackware box with IPTables 
in the same setup, Internet -> Firewall -> SMTP Server and port 
forwarding. Milter-greylist was working fine. Now I'm using a router 
with a NAT and SPI firewall (linux OS). I didn't connect the greylist 
problem with the firewall change. I guess this could be the problem. If 
so, is there a way around it?

Thanks,
Rick
