Matthias, assuming that you create an Additional Address "Mail" on the External internface:
SNAT : External (Address) -> SMTP -> Internet : from External [Mail] (Address)
Did that do what you want?
Cheers - Bob PS The same would be true for "Web Surfing" instead of "SMTP." The solution is different if you have two WAN connections and are using Uplink Balancing.

Bob, I don't know if I am getting you right,but isn't the suggestion you do the same I did describe in my update?
I don't know if I really could point out what I need: SMTP Server1: 192.168.1.1 /24 SMTP Server2: 192.168.2.1 /24
WAN1: physical WAN IP 46.1.1.1 (ISP does not allow PTR records on this address) WAN1: additional_address_1: 46.1.1.2 (PTR company1.com) WAN1: additional_address_2: 46.1.1.3 (PTR company2.com)
So how could I configure UTM 9 to translate Server1 to 46.1.1.2 and Server2 to 46.1.1.3?
