There is a slight workaround. One can distribute the original + source + 
patches and a script that does the patching/installing. Hence the 
netqmail-1.05 version.

Les, quit making false statements about qmail. qmail does not have any 
logical flaws otherwise Wietse would not follow the same design 
principles in postfix after his spat with DJB. qmail's problem is that 
the author has not done any updates to it since 1998 to handle the 
changed needs required of a MTA software since then. SMTP is broken 
which is why spammers and virus writers can create so much trouble. Both 
SMTP and qmail were designed in an environment very different from what 
we have now. That is why we have ESMTP and what not updates to the SMTP 
protocol.

qmail is a fine piece of software and it also introduced the maildir 
format which is now widely supported and used by anyone who cares about 
the integrity of their mailboxes. I cannot understand what you have 
against qmail to go around bad mouthing it. Don't tell me a stuffed 
queue and perhaps a listing in some over zealous RBL was all it took.
