SBS 2003 not receiving a specific email

Good day,

I have a problem emailing out of an Elastix machine. or the problem could be receiving emails on an SBS 2003 server.

Basically, If I send an email to myself (user@domain1.net.au) from the Linux console I can receive it fine. However, if I send an email to user@domain2.com.au the email is not received.
The Elastix machine and the server (Exchange / SBS 2003) for domain2.com.au are in the same LAN and share the same Pfsense firewall.

If the email to domain2.com.au is sent from a remote Elastix server it is received.

So i guess the issue must be happening because the Elastix server i need to configure is on the same local network as the domain2 SBS.

On the firewall, I've forwarded ports 25 and 100 to the SBS server.

What am I missing?

TIA

Can you clarify the below things.

domain1.net.au and domain2.com.au  are they both hosted on SBS server.
Does Elastix machine host email as well.

ASKER

mail.domain1.net.au - Windows Server 2003 STD running Exchange Version: 6.5.7638.1

mail.domain2.com.au - Windows SBS 2003 with Exchange Version: 6.5.7226.0
The Elastix machine (CentOS release 5.3) runs postfix. It just sends emails with Hylafax; it attaches the faxes to an email and sends them automatically to a nominated address.

Thanks
so from the SBS LAN can you telnet to mail.domain1.net.au  on port 25.
