# 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
