I'm trying to run a mailserver on a spare G4 in my office using
Postfix Enabler. I can send mail out using my ISP's outgoing mail
server but would like to receive mail for the account using Postfix's
mail server feature. The documentation seems straightforward but I
can't get it to work. I'm not an expert on the subject by any means,
so I'm hoping somebody out there might be able to point out what I'm
doing wrong. I'll try to provide as many details as possible:

I'm using a Netgear router with a G4 400mhz running Panther. My ISP
gives me a dynamic IP so I'm using DynDNS.org so "mydomain.ca" links
to my server. My web server and FTP server run fine.

My router has a local address of 192.168.0.1.
The G4's address is 192.168.0.3.

Router:
I forwarded port 25 to the G4's server IP address of 192.168.0.3 and
did the same with port 110.

Postfix Enabler:
I set the Domain Name to mydomain.ca, set the root under "aliases" to
my short user name for the G4, and under "Access" I added 192.168.0
RELAY as per the help doc's instructions. I left everything else at
the default settings, enabled POP3 and started Postfix.

Mail App:
I specified an email address of myshortusername@mydomain.ca. I set the
user name and password the same as my short user name and password for
the G4's user account.

I also specified an MX record of mydomain.ca in the dyndns.org
settings and included this in the DNSUpdate client's host settings as
well (wasn't sure if I needed to do this or not, so I did).

I tried sending the account mail. When I check it using Mail, it seems
to access the server properly but never finds any received mail.

If anybody can offer me some help as to what I'm not doing/what I'm
doing wrong, it would be greatly appreciated!

Thanks,

Jay
