He doesn't (not that it turned out to matter this time).  There's nothing added 
to the package Ubuntu got from Debian that related to upstream fixes.

That said, back when I was involved in Ubuntu development, I did secure special 
permission to update Postfix for third digit updates based on the demonstrated 
history of such updates being confined to actual bug fixes and being high 
quality with low regression risk.

Since I stopped working on Ubuntu, no one has done the work.  I know there are 
more than a few Ubuntu users here.  If you want the distribution to deliver 
post-release updates of Postfix, then all it takes is someone volunteering to 
do the work.

I don't have time to do much in the way of training, but if anyone is 
interested in taking this up, feel free to contact me off list and I will point 
you in the right direction.
