# DEV Notes:
# * the first regex is essentially a copy of pam-generic.conf
# * Probably doesn't do dovecot sql/ldap backends properly (resolved in edit 21/03/2016)
# * Removed the 'no auth attempts' log lines from the matches because produces
#    lots of false positives on misconfigured MTAs making regexp unusable
