Sure, but there is a good reason here: Emacs movemail supports only
unencrypted POP3 connections, which has real security problems in
typical network environments today. Also, as can be seen earlier in this
thread, having two 'movemail' commands confuses users and can trip them up.
I take your point that there is a backwards-compatibility argument for
installing a movemail program that converts mailboxes from system format
to Emacs format, when GNU Mailutils is not available. However, we should
not distribute a movemail program that encourages users to read their
mail unencrypted over a network -- although that may have been OK in the
1980s when POP support was added to movemail, it's a grave disservice to
users in typical environments today.
Attached are two proposed patches to try to improve the current
situation. The first removes unencrypted POP3 support from Emacs
movemail, as it's a significant security blunder to insist on
unencrypted network connections these days. The second changes the Emacs
build procedure so that there is a configure-time option for whether to
install the substitute 'movemail' program instead of relying on GNU
Mailutils 'movemail'; the idea is to let distributors decide whether to
make GNU Mailutils be a prerequisite for reading email in Emacs.
