Обсуждение: SQLRelay?

I just saw someone mention SQLRelay on the postfix-users mailing list, and it
seems like a really cool project.  I haven't heard of it though (which is
kind of surprising, since I've been looking for something like this for a
while) so I wanted to see if anyone here has any experience with it.
