Moving towards a "all-PAM" behaviour is barely what upstream is
doing. And we'll try to stay as close as possible from upstream.

What I propose above goes this way and is very close to your 1. proposal

So, Tomasz, I'd really like to have your advice on this #330240 issue.

Actually, I made some testing and I really wonder what *exact* role
plays MAIL_DIR in /etc/login.defs. Commenting it does not prevent
users to have a properly set MAIL variable as long as pam_mail is in
login and su PAM config files...while suerdel still deletes the user's
mailbox when called with the -r switch.
