i have a dmz with a mail server - i want that mail server to use the same public ip 1.2.3.24 when it sends email to the world.
currently it will send mail but using the public ip all the inside users use. this is urgent b/c we dont want to get blacklisted.
i'll attach part of the config.

global (outside) 1 interface
global (outside) 10 1.2.3.24
global (DMZ1) 1 10.10.5.0
nat (inside) 1 0.0.0.0 0.0.0.0 0 0
nat (DMZ1) 1 0.0.0.0 0.0.0.0 0 0
static (inside,outside) tcp x.x.x.x https 172.16.1.34 https netmask 255.25
5.255.255 0 0
static (inside,outside) tcp x.x.x.x https 172.16.1.17 https netmask 255.25
5.255.255 0 0
static (inside,outside) tcp x.x.x.x https 172.16.1.35 https netmask 255.25
5.255.255 0 0
static (DMZ1,outside) x.x.x.x  10.10.5.10 netmask 255.255.255.255 0 0
static (inside,DMZ1) 172.16.1.0 172.16.1.0 netmask 255.255.255.0 0 0
static (inside,outside) x.x.x.x  172.16.1.24 netmask 255.255.255.255 0 0
static (DMZ1,outside) 1.2.3.24 10.10.5.2 netmask 255.255.255.255 0 0

>static (DMZ1,outside) 1.2.3.24 10.10.5.2 netmask 255.255.255.255 0 0
This static should already guarantee that this dmz1 host uses 1.2.3.24 for outbound.
Just try issueing "clear xlate" or reboot the PIX
You can also remove this:

thats what i thought too.
we finally got it to work by changing the commands below - the rest of the config remains the same.
nat (DMZ1) 10 0.0.0.0 0.0.0.0 0 0
static (DMZ1,outside) 1.2.3.24 10.10.5.2

thanks for all the help. the email solution is now in production and working great.
this site really helped me understand the functionality of the pix.
