Wietse, in a post[1] on the Postfix mailing list, lends further credence
to a suspicion that this issue is particular to pointyhat:

 Postconf opens a socket to determine the mynetworks value (it
 determines the local interfaces and their netmasks).

 I have heard about bizarre errors on FreeBSD (jail) systems where the
 user-land library was out of sync with kernel-land, resulting in data
 structure mis-matches and system calls returning nonsensical results.=20
