And it's not always implicit, either. Having him on a technical mailing  
list does make for frequent flame wars, in every case I've seen.

Multiple simultaneous SMTP connections are, of course, highly antisocial  
to the host at the other end. And if multiple sequential SMTP connections  
are faster, then somebody is doing something very wrong here.

I consider them very serious. Besides, the author's attitude problem  
applies to standards, too, another point I find unacceptable.

I find myself completely unable to trust him. So, qmail cannot be an  
option for machines I administer.

I should probably mention that I have similar trust problems with  
sendmail. Besides the sendCERTadvisories problem, I have trouble trusting  
a program when it's author admits that he purposefully inserted a back  
door in that program (it's the DEBUG hack that made the Internet Worm  
possible - it was meant to give root access to the main sendmail test  
machine, because the author didn't have the root password).

What isn't about 1000 times easier to set up than sendmail? :-)
