[sliken]

Not sure I see the justification replacing postfix (which with simple configurations can be configured with just a few lines in a config file) with haraka written in javascript.

Unbound seems generally respected, is nice and simple, written cleanly, and does MUCH less than bind. However it has had at least one memory corruption bug that plagues most c/c++ applications of non-trivial complexity. It also does seem to hang and I ask around and other people have seen similar. It's no longer what I consider reliable enough to be installed on every client. It's scary that it hangs, because if it gets that wrong there's likely other issues as well.

I'm hopeful that SDNS is more reliable and secure. I just want a local caching resolver that understands DNSSEC.
