"mydomain.com" "mydomain.com" "" "2008-11-16 19:00:26" "example.com" "" "" "" "" "AUTH=EFAIL:TYPE=CRAM-MD5" "" "0" ""

"mydomain.com" "mydomain.com" "" "2008-11-16 21:15:01" "example.com" "" "" "" "" "AUTH=EFAIL:TYPE=LOGIN" "" "0" ""

...where aka example.com is the offending host.


The regular expressions below are proposed failregex for this software. Multiple regular expressions for failregex will only work with a version of Fail2ban greater than or equal to 0.7.6.

The tag <HOST> in the regular expressions below is just an alias for (?:::f{4,6}:)?(?P<host>\S+). The replacement is done automatically by Fail2ban when adding the regular expression. At the moment, exactly one named group host or <HOST> tag must be present in each regular expression.

Please, before editing this section, propose your changes in the discussion page first.

failregex = ".*"	".*"	"<HOST>"	".*"	".*"	".*"	".*"	".*"	".*"	"AUTH=EFAIL.*"	".*"	".*"	".*"
