I have 2 domains, electrichendrix.com and mytimewithgod.net. Both are
through dyndns.com as i have 1 dhcp address from my provider. Both
domains have a mx record in dyndns.com's system. It doesn't really
matter, as mail going to mytimewithgod.net is pointed to the same ip as
electrichendrix.com and i have no problem getting mytimewithgod.net mail
on my mailserver. Passed this isp connection i have a juniper firewall
that does nat or more appropriately, pat. Behind this firewall, sits the
192.168.x.x subnet and the 192.168.x.x subnet. These subnets are
connected via switches to the firewall. On these subnets, i have a DC, a
mailserver and a webserver. It is funny that mytimewithgod.net does not
report a mx record; i am looking at the mx right now on dyndns.com.
Anyway, mytimewithgod.net is making it to my mailserver and being
forwarded to the webserver which has mailman installed.

Here is the problem, i believe.......mail from the mailserver is being
rejected by the webserver as "relay access denied". On the webserver,
which has postfix, in main.cf i have entered relayhost =
main.mail.server but i still get the same response "relay access
denied". I have asked on the postfix mailinglist, how to have postfix
accept mail from my webserver. Still waiting for a reply.
