Browse All TopicsWe are still running Exchange 2000, behind a Sonicwall 2040 Firewall - everything works, life is good. I just purchased a Sonicwall Email Security Appliance Model 200 to offload the spam filtering from the Exchange server.
Set it up per the book & pointed the firewall to it, and it to Exchange.. Nada
When I tried to telnet on port 25 from the command line on the spam device, I just got "Connection closed by foreign host" 100% of the time. Tech support basically said it's an Exchange problem.
I created a computer in AD named same as the spam device & now get a 220 connect from telnet but it won't accept any further commands...
I've been beating on this for about 2 weeks & SW tech support on it for 8 hours..
Anyone with any insight PLEASE.......
