[arch-general] Hardlock after postfix/smtp entry in log - leaves 4 lost inodes each time - ideas?

So, to read that log for humans, is establishing a
connection on port 25, dropping an email to
scherer at schererinvestments.com... next thing, bind tries to resolve
clickme2.click2site.com/AAAA/IN and fails to connect to the network
with "network unreachable"...

further questions:
- Is postfix supposed to accept connections
  * from outside?
  * on port 25 (unauthenticated smtp)?
- Is bind supposed to
  * accept connections from outside?
  * fail on that lookup?

Are in the breakage both or only one of those services involved?
[1] is not the kind of lockup you're talking about, or IS IT?
Does the problem occur with community/unbound [2]?
