Help with getting Mail to my mail server on DMZ

JamesSteen
I have a mail server I just set up on the DMZ. Main network is setup as 192.168.0.1 DMZ is 10.0.0.1. I do have a Masquerading rule for 
"Internal (Network) - DMZ" I also set up "Not sure if needed" 
"DMZ (Network) - External (WAN)"
I do have a somewhat unique situation as I get my mail from DYNDNS since I do not have a static IP. So my
SNAT = SNAT Mail Server
Traffic selector: External (WAN) (Address) → SMTP → DYNDNS - Incoming
Source translation: SMTP - 2525
Automatic Firewall rule:

DNAT = DNAT Mail Server
Traffic selector: DYNDNS - Incoming → SMTP - 2525 → External (WAN) (Address)
Destination translation: SMTP
Automatic Firewall rule:

Firewall rule is =     Internal (Network) - Any - SMTP - 2525

Thanks to any and all who may try to help.

    Sorry, I don't understand.  Please click on [Go Advanced] and attach pictures of your NAT rules.

    If you need an "Internal (Network) -> DMZ" masq rule, you have a Host definition that violates #3 in Rulz.

    Cheers -  Bob
