Hello, I've tried all I can think of to get CommuniGate to relay smtp
email so people I host can use the php mail() function. However despite
my efforts mail in the que for sending through smtp times out.
CommuniGate resolves the mail servers dns names and IPs but returns a
error of 'No response from "mail server here"'. I have already
unblocked the following tcp ports: 106,110,8100,25,143,8010,and 674 but
to no avail. I have made sure the mx dns records for my domain
johnscompany.net are in order as well. I am running CommuniGate version
4.2.9 PPC and am using the linux distro YellowDog Linux 4.0.1 as well
as Apache 2.0.51, php 4 and mysql 3.xx. Any ideas why the mails aren't
sending? Do I need to unblock some more ports? Any help is greatly
appreciated.

Thanks!

Drop the firewall for a quick test...

Off the top of my head I think you ar missing one or two...

25 seems to stick in my mind, but at this time of the AM I could be wrong..
