I have a network of about 30 users. We are migrating from a Windows environment to Macs. We currently have a Windows 2003 server hosting the email accounts with the help of an external spam filter. These addresses receive a lot of spam each day and legitimate emails get caught in the spam filter each day. The current IT person checks the filter four to five times a day.
I have two questions needing some input from someone with experience.
Should we continue to host email internally (with the external filter) from the Xserve SLS or switch to an external host entirely?
If we switch to an external host, which host provides good spam filtering?
