Zentyal Zarafa -Sending mail to .lan and .com domains

[shahsx]

Hi Guys,

I have set up two Virtual mail domains in Zarafa, one is a .lan and one .com. I want the .lan domain to just send mail localy within the internal domain and .com to be able to send mail as normal. Is this possible with Zarafa and what's the best way of doing it.

Thanks
Sagar
