At work we're looking to get a new email server, we prefer one that runs on Windows though we do have a Unix box and we could run it on Linux. I am open to suggestions. We've been using this lamo server and we're done with it after it crashed the other day. Spam is pretty huge coming in though after a week with filters it is very minimal coming into peoples mailboxes. Anyways. Any suggestions? We have under 75 users.
