NAT rules not working

I configured a segment of my /16 net as a specific definition. In this case 172.22.105.0/24 (subnet1).
The target I wanted to achieve was, to do a source NAT for that networkgroup over a second external IP address I've configured on the wan interface (extip-2).
Meaning, that every traffic which originates in that subnet should do a NATing through extip-2.

What I did was the following:
I configured

- a masquerading from [subnet1] to [extip-2]
- S-NAT
    Traffic Selector: [subnet1] -> SMTP -> [extip-2]
    Source Translation: [subnet1-ip (.100)] SMTP
    Automatic packet filter rule: Yes
    Initial packets are logged: Yes
-  No changes in Packet Filter

But still, I only get emails from [extip-1] which should be from [extip-2]
if the NATing would work.
Anyone here who can help me with that, or give me some simple explanation how to accomplish that?
Any help would be great.

One addition. The NAT rules I've created did not create a specific Packet Filter rule.
Which makes me ask, does the "auto packet filter rules" option really work?

Hi, I believe the
Traffic Selector should be
Source: subnet1
service: SMTP (or ANY if you want)
dest: Internet

and Source Translation should be
extIP-2

You won't see an 'Auto PacketFilter Rule' listed on the PacketFilter page. Because of that, I prefer to create my own, but both will work.
