"q" in "qmail" means ?

[Dave Kitabjian]

I ask this question with great trepidation.  Either I'm the only one brave 
enough to ask, or I'm the only one stupid enough to have to ask, but...

What does the "q" in "qmail" mean?

Dave

p.s. Since I'm going to get flamed for stupidity, let me ask another 
question:

If LWQ insists that the official name is "qmail", not "Qmail", why does the 
logo start with "Q" on http://www.qmail.org/top.html?
