As I understand it, the licensing for qmail basically says that you can distribute the source code, distribute patches to the source code, but not distribute any binary copies. Is that accurate?

Well, one thing you could *try* is reading the qmail license (or rather, DJB's notes for distributors, as qmail technically has no associated license). It's essentially two short paragraphs: http://cr.yp.to/qmail/dist.html

READ IT.

Anyone who wishes to distribute qmail ***MUST*** read DJB's notes to distributors FIRST. You cannot, in good conscience, rely on the advice of third parties without knowing the facts of the situation for yourself.

Based on that, would I be allowed to distribute an SRPM with the original source and all my patches? (Please, no flamewars about my choice of packager) Or does that violate the licensing?

Well, let's see:

    You may distribute copies of qmail-1.03.tar.gz, with MD5 checksum
    622f65f982e380dbe86e6574f3abcb7c.

In other words, if your SRPM contains a copy of qmail-1.03.tar.gz whose MD5 checksum is as listed, then yes, you can distribute it.

I believe there's another package that distributes qmail in a binary form, though the name escapes me at the moment.

You're probably thinking of Plesk, and the exact status of what they have done is really rather nebulous (DJB has never clarified). Our only assumption can be that Plesk is distributing binaries that appear qmail-esque, and nothing more.
