for some reason I can't make a connection to the external mail server from inside the lan. even from the 10.0.0.3 address which should be allowed to do anything.
everything used to work when i used MASQUERADing but stopped once i switched to SNAT. 
Can anybody help me? What am I doing wrong??

Thanks
