I'm looking for an email GUI that runs on Linux, preferable Fedora or Debian. I need something that will integrate Anti virus and anti spam. Basically looking for something like cpanel but specifically for email. I can use cpanel, but it's a bit of overkill since there will be no hostin on the server. Willing to look at anything from free to about the cost of a cpanel license, but it must be robust and reliable, and able to do the anti-spam and antivirus.
