Thanks Stefan, Nice analysis - esp. of the locking problems which explains why I wasn't managing to scale with multiple threads, even from a straight python script (no Zope). Pretty certain I'm going to botch up qmail if I start writing directly to the maildrop, but will investigate. As for my initial question (detaching the sending thread from the interactive part of Zope), I'm relieved to see that the 'threading' module is taking care of everything for you ... I must have screwed up in my earlier attempts (using 'thread'). Will give it another shot now that I know this is the way to go forward.
