The author tends to implement what he things IMAP *should* be. Me? It's intereresting, it's young. I use Cyrus, I've used Sendmail, Inc's server. The Sendmail plus is that it's a pkg_add (or rpm) to install and a couple minutes of config - I did it a lot, I can get it running in 10 minutes. It scales huge (100k isn't an issue if you don't use candy ass RAID). The minus is that it costs and if you want Sieve, that costs more. Cyrus doesn't scale quite as high, but it scales quite well. But this is not qpopper, the topic of this list. qpopper can scale to 100,000 users with the right hardware. Earthlink used it at 3million over NFS with some mods to locking and such. Ban your shell users (it's a pop server, not a shell machine). IMAP (iffy) and POP. That's it.
