Looking for a low cost easy to use mail server - we've had EMWAC running for 10 years - would like to retire it and get something that can handle 5-10 mail boxes but don't have alot of money to spend, and would like something easy to use - we need just the basics with good filtering capability. Any suggestions? We should have done this years ago but hard to stop using something that works without thought. With new operating systems coming out I'm sure we will run into a block with this ancient software. Would appreciate any suggestions before this becomes critical. We use IIS6.0 / 2003 server for the websites. We run the email server on a xp workstation.
