Re: [cobalt-users] Sending e-mail behind firewall

["Franklin S. Werren" <fswerren@xxxxxxxxxxxx>]

Hmmm....
Turn on Smart Relay and use your ISP's Mail Server
It looks like you are being blocked by a router....
Some of the better ISP's are blocking outgoing port 25
to try to stop spammers and viruses on their internal system
from being passed around....
My ISP did the same thing....
You do have your DNS on the box turned on ????
