Postfix defualt rule

[toomanylogins]

Hello,

I seem to struggle with creating rules some sort of mental block. I previously had postfix setup on a guest and it was working okay using NAT rule. Just set up the postfix plug-in and after following the instructions the last paragraph is as follows.

"In the next step, you should go to the Firewall menu. Create a new rule to pass port TCP/25 traffic from Any to This Firewall."

So new rule on WAN interface as follows ?

Interface WAN
source any ?
source port 25
Destination This firewall?
dest port 25

In logs I am getting incoming to the dest is wan address and blocked

Can someone put me out of my misery.

Thanks
Paul
