Considering that lockfile(1) is usually installed as part of procmail, and
is not part of the base system of FreeBSD, NetBSD, Solaris or Linux, it seems
fairly safe say that lockfile(1) is not defined by POSIX.

It might be that you meant lockf(1) though, which is part of the FreeBSD
base system.  It is not part of either NetBSD, Linux or Solaris though and
the FreeBSD manpage makes no mention of standard compliance, which means it
is most likely not defined by POSIX either.
