215	Use LDAP to determine whether users receive mail	mitchb		"We presently queue mail for locker@scripts.mit.edu when
a locker isn't signed up for the mail_scripts service
because the only way to determine that is to check for
existence of /mit/locker/mail_scripts/procmailrc, and we
could mistakenly conclude that the file doesn't exist and
drop users' mail during an AFS issue.

We should modify our LDAP schema to store a boolean for
whether a user should receive mail.  We should default
this to ""false"" for new accounts, and set it to ""true""
when a user runs signup-mail.  For existing users, we
should set it to ""true"" for anyone with a procmailrc
and ""false"" for everyone else (unless they're specially
handled in /etc/aliases or something).  We should then
either get Postfix or procmail to check this value
and discard mail immediately if it's false.

This will alleviate much of our mail queue growth issue.
