That is a good suggestion as well .... but the mail worked before I installed the firewall. .... I am coming up at a bit of a loss ... I checked the logs last night. When I try to send or receive mail I get an error saying can't connect to the pop or smtp servers, but there is no entry in the firewall log for the error ( and as far as I can tell .. I am logging everything ..). ----- Original Message ----- From: "George Vieira" <georgev@xxxxxxxxxxxxxxxxxxxxxx> To: "Peter Marshall" <peter.marshall@xxxxxxxxx> Sent: Monday, September 08, 2003 7:50 PM Subject: RE: email through firewall > Try changing the MTU of the firewalls outgoing packets.
