With 1:1 NAT, you first create the mapping in the 1:1 NAT tab, then  
you must create a firewall rule that allows it to pass to the LAN  
address.

For Server NAT, you first create the mapping in the Server NAT tab,  
then you must create both an INBOUND NAT rule and a FIREWALL rule to  
permit routing to the LAN address.

Destination is always the LAN address. Rules are whatever ports you  
wish to open, such as 25, 110, 143, etc. depending on what mail  
server services you are allowing.
