Qsmtp 0.10
This night I released officially Qsmtp 0.10. For those who don't know: I've written a drop-in replacement for qmail-smtpd and qmail-remote called Qsmtp. The new version is more or less a bugfix release. New features focus on better SMTP standard compliance and even better spamfilter capabilities.
I also began working on a replacement for the scheduler in qmail-send. If you have a mail to multiple remote recipients qmail-send will fork one delivery process per recipient even if all share the same receiver MX. Qrschedule should do what every other mailer already does: find out which recipients belong together, then do the minimal possible number of deliveries. What is already there is the part that does the routing decision. In my experiments it worked very well. Still missing is everything else: integration into the delivery chain, handling of bounces and so on. It's a point to start playing for everyone interested. Getting this finished will take me at least 2 weeks of fulltime coding, so if anyone steps up with some money...
The important changes are in the changelog, Qrschedule can be found in the subversion repository.
