I'm currently on a Windows Server 2003 64-bit, core2quad Q9300 (2.5ghz), 8gb of ram. I'm using hMailServer but have decided to switch to something else that ties webmail, anti-spam, etc all up in a nice package.
I've come to the decision to go with SmarterMail and just wanted to gauge opinions on their software here. I know in the past I've seen good comments on SmarterMail but wanted to make sure the general opinion is still positive.
I was really surprised there was no overall website with a matrix for Windows-compatible mail servers, it was rather tedious to go through all the different servers to see what they had to offer but SmarterMail just seemed to be the best "bang for the buck" server.
