Escaping From_ lines is necessary only for software which uses mbox
format.  Thus, software which uses mbox format should take care to
escape From_ lines.

pop3-movemail is a function which uses mbox format (as its output), so
it should escape From_ lines.

pop3-movemail should not depend on the fact that the SMTP
implementation or the POP3 server use mbox format anywhere -- that is
not at all a given.
