# yp_nomail
#
# Our mail admins got annoyed when bugzilla kept sending email
# to people who'd had bugzilla entries and left the company.  They
# were no longer in the list of valid email users so it'd bounce.
# Maintaining the 'data/nomail' file was a pain.  Luckily, our UNIX
# admins list all the users that ever were, but the people who've left
# have a distinct marker in their password file. For example:
#
# fired:*LK*:2053:1010:You're Fired Dude:/home/loser:/bin/false
#
# This script takes advantage of the "*LK*" convention seen via 
# ypcat passwd and dumps those people into the nomail file. Any
# manual additions are kept in a "nomail.(domainname)" file and 
# appended to the list of yp lockouts every night via Cron
#
# 58 23 * * * /export/bugzilla/contrib/yp_nomail.sh > /dev/null 2>&1

# Tak ( Mark Takacs ) 08/2000

# XXX: Maybe should crosscheck w/bugzilla users?
