I am hosting 5 email domains on one server,  the server has 5 different invalid Ip addresses.  I setup static nat on the firewall, however when I send email from any domain it says its coming from the firewall and not the valid Ip I have static nat-ed to the invalid ?  Does anyone know what I can do to fix this issue ?

As it stands, it looks like your server is sending out email via its gateway, which is probably the IP of the firewall.
You probably need to "convince" your hosting server to send each domain's email using the internal IP you want.

You can test this by configuring your server to use one IP of the five, send a message, then configure to use another of the five, then send another test message, and so on.  Your sequenced test messages should appear as if coming from each corresponding external IPs.
If that does not happen, your static NAT is not working.  If that does happen, it is a server problem, not network.
Test and let us know.

Actually I found the answer- the 1 to 1 was all setup in watchguard, however you have to add each invalid Ip in the dynamic nat tab so it should look like this. to External to external

So after al l the one to ones are seutp you put in each invalid ip in the dynamic nat exceptions.
