# DEV Notes:
# * the first regex is essentially a copy of pam-generic.conf
# * Probably doesn't do dovecot sql/ldap backends properly
# * Removed the 'no auth attempts' log lines from the matches because produces
# lots of false positives on misconfigured MTAs making regexp unuseable
#
# Author: Martin Waschbuesch
