Im new to Zimbra and i'm gonna install it for a midsize business (150-200 accounts). Im just worried because of the characteristics of our setup.
It is a rather far office (20kms away from the nearest city) and because of that we cant get hi-speed internet.
I want to be able to send emails to the outside world, not only the domain (companyname.com).
So the question is, is it possible for emails sent to email@example.com to be send over the lan, not the Internet connection, and only have emails sent to other outside domains (firstname.lastname@example.org) leave the LAN?
