So we're not seeing that crash on the experimental build daemons in
debian.  that makes me think that something is amiss with the
dependencies in jessie, or maybe we've failed to indicate some
dependency correctly.

gniibe (cc'ed) is usually the person to sort out scdaemon issues --
perhaps he can suggest some next-steps for debugging?

fwiw, my messages were recently bouncing from this mailserver too -- i
had to fiddle with some DNS records for my own mail relay to get
kerckhoffs to accept mail.  it's possible that the spamfiltering rules
have been tightened up recently, or the DNS resolver has changed.

I note that has no PTR record at all.  maybe the gmane
folks need to add a reverse DNS record via their hosts at
