Postfix

configuration

[John_Keates]

Hi, I have Mac OS X 10.4.10 and postfix... The only problem is that I don't know how to configure it correctly.

I have this setup:

Outside ip -> Router -> DMZ / G5 with direct access

DNS:
MX ASPMX.L.GOOGLE.COM. 1
beta MX beta.mydomain.com 10
beta MX mailrelay.planet.nl 20
dev MX dev.mydomain.com 10
dev MX mailrelay.planet.nl 20

What I want to do is have postfix receive any mail sent to mydomain.com
Outgoing mail is going via a relay: mail.planet.nl
(planet is my ISP so I guess I can post it and I'm not sponsoring them in any way...)
that is because they have a spamblock for outgoing mail.

So I set up mydomain.com to be done by google's mail service, and all subdomains should be handeled by my local mailserver (which is done by an incoming relay, mailrelay.planet.nl). I never got it to work... I have outgoing working and I have the main incoming via google but the subdomains don't work...

Does anyone know how to do this?

I'm not saying this will fix it, but this is a good read: www.syntheticzero.com/howto/vmail.php and so is this switch.richard5.net/isp-in-a-box-v2/

I'm trying to do pretty much the same thing, BUT, instead of opening up ports locally, I'm trying to get Postfix to log into a POP3 mail server and download the emails every few minutes. This may sound unconventional, but I see it as a) more secure (less ports to open and so on), b) safer (if my ADSL line fell, I wouldn't lose emails), and c) more flexible (I wouldn't have to wait for MX TTLs to change my server's IP).

But figuring how to do it is the tricky part!
