I'm sorry, this is probably a really obvious question, but could you
explain the connection between the subject of your mail message and the
body of your mail message? I can't see any relationship, so I guess I
need it spelled out for me in small words.
(I believe /etc/shells enforcement is done via PAM or in specific
programs that impose this as an additional non-POSIX restriction. This is
outside the scope of POSIX.)
