I'm looking into mail servers for Windows 2000 and damn they are expensive! So far I took a look at exchange, but that costs around $700. I also took a look at Sendmail for NT and that seems really good, but it costs about $500. I checked out download.com and downloaded a few free ones, and they were just terrible.

So can anyone recommend a decent mail server that runs on windows 2000... preferably one that doesn't cost an arm and leg.

Thanks!
