Can you go to a prompt and ping servername.domain.com ?? If you don't get resolution to the IP address then you have a name resolution problem. If so, try configuring your email client to use the ip address instead of the server name. Don't forget, If you have added filters, you could have inadvertantly filtered external DNS traffic. -----Original Message----- From: Roy Morden [mailto:roy@xxxxxxxxxxxxxxxxxxx] Sent: Friday, September 07, 2001 3:47 AM To: [ISAserver.org Discussion List] Subject: [isalist] cannot connect to external pop and smtp server http://www.ISAserver.org we have our email hosted for us, so clients need access through the isa server for pop and smtp, however all we get is server not found. Is this an isa problem or name resolution?
