That's not my understanding.  I've got /usr/lib/sendmail linked to a qmail 
gizmo, and it's been working for months now.  It says so in the qmail docs.

Is there something I'm missing?

Also, the Sendmail.py-based Mailman stuff appears to be working with no 
problems for me (other then the warnings from the Mailman developrs not to 
use it...which is why I'm in this investigation).

Yes, this is a viable option.  What more can you tell me and/or what 
references can you give me?  I invite you to take conversation "offline" 
from the list if that's more appropriate?

One curiosity:  I'm curious if Postfix can support virtual domains as well 
as qmail can?  (Maybe that's hard to answer if one does not know 
qmail.)  When I first looked at Postfix, the seemingly massive amount of 
script/config-file setup was completely overwhelming to me...or was that 
exim I was checking out?  There was some specific set of reasons why I 
chose qmail over Postfix, but I can't remember them.  The fact that 
yahoo.com and smtp.com both seem to be qmail-based systems have a large 
pull with me, though; I get the impression Postfix hasn't been around the 
block as long as qmail, but that does not mean that it's not stable.

Did I just start a postfix-vs-qmail rat hole?  (That could probably help 
me, but it may take away from the list.)
