I dunno, I use qmail + vpopmail + about half a dozen very small (and easy to 
verify) patches + rav's qmail-queue and haven't run across anything screwey 

Now of course the whole point of DJB's license is that you can't release a 
version with all of this applied already.  It's unfortunate but I've got it 
down to one combined patch and I have an internal package I use for my mail 
servers.  Good enough for me, and qmail is a really good piece of software; 
too bad it's ugly.  I'll take ugly and functional for server software any 
day, though.  Just don't ask me to install djbdns or svc. <shudders>

I don't take all of Dan's postings to heart.  He's a pure academic and as such 
his world is full of perfect situations.  I use qmail with ext2/ext3 with 
noatime and async.  I've got the systems on a UPS and they'll shut down nice 
if something happens to system power.  I've yet to have a kernel/system crash 
on a production machine so, to me, all of his hand waving about sync writes 
and so on are just that: hand waving.

I didn't see either of these mentioned in the link.  Is that elsewhere?
