I started using qmail in 1996-ish, and was a pretty big fan for a while. I wouldn't use it at this point though, it really has languished and is, IMHO, totally unusable without a lot of dicking around to get the right set of patches and the like. He kind of lost me when AOL increased their MX record to be larger than UDP could handle in a single packet. He stood firm that AOL was doing it wrong, meanwhile my users didn't care about what the RFCs said, they just wanted to e-mail their grandma like all their friends could. The qmail community collected a lot of people with similar personalities and I got tired of it. These days, I'm pretty happy with Postfix, and it has things a modern e-mail servers needs, supported in the core rather than requiring a ton of patches that haven't been eyeballed by the author.
