What mail protocol(s) do you use: SMTP, POP or maybe MSX-RPCs (the 
latter will be a problem).

If you use SonicWall in NAT mode make sure you set 1:1 NAT so external 
servers can connect to the MSX.

Test: can external servers ping your MSX? If not, routing and/or NAT are 
wrong, even if you can get out...
