You are correct ;) Sendmail can only sustain one exsistance of it's 
delivery object meaning it can't multithread like the newer MTA's soo 
when sendmail runs a large q say 10k messages all those messages go into 
q and get piped out through one thread instance of sendmail whereas qmail 
simply fires up 500 threads and crunches through the q message by message 
until it's done. You can also reconfigure qmail to allow up to 1k 
concurrency and if you really want mailing power you can edit and 
recompile your system and qmail and go up as high as you want. I have 
mine set at 800 on 6 different servers and have never had a bootleneck... 

Anyways theres my two cents .. Now I go home and sleep (trying to 
remember what that word actually means)
