This is very strange. My port 110 failed to get incoming mails from external. It works after I powercycle the computer, the firewall and the router (not sure which one fixed it). I can send email, I can get on the internet, except getting external emails. LAN email works fine.
Here's my setup
ISP Frame Relay -> Cisco 1700 router -> Cisco 3500XL switch -> Netscreen10 -> Cisco 5500 switch -> Microsoft ISA -> Imail 8.0
something is killing port 110 either at Cisco 1700 router, 3500 switch or the netscreen10. It will go down every night and weekends, then I have to reset the router, firewall or the switch.
I am running active directory. Could this be the problem as well?
