Hi ,

Assuming that IP address of mail server is 1.1.1.1, you may try using following commands-

access-list pol1 permit tcp host 1.1.1.1 any eq 25

nat (inside) 10 access-list pol1

global (outside) 10 interface

static (inside,outside) tcp x.x.x.219 25 1.1.1.1 25

Note: If you are already using outside interface IP for outbound connections as shown in following example-

nat (inside) 1 0 0

global (outside) 1 interface

In this case, you dont need the first 3 commands.

Let us know how this goes.
