At some time during last months (I can't give exact dates, sry) something
broke postfix using kqueue(2) (it's default for DragonFly). I've used
postfix for ages on my machines, now it starts up, is able to receive
even some mails at best, but stops responding then. I'm able to telnet to
the port 25, but postfix doesn't respond.
$ ps axl | grep master

At all kqueue(2) seems to be extremely fragile in DragonFly. There are
many packages using it probably just via autodetecting it, but there is
packages known to be broken in DragonFly for ages while built with
kqueue(2) support. Sysutils/dbus is certainly most notable such one -
kqueue(2) support works on every BSD except DragonFly.
