Exim

From Fail2ban

Exim is a mail transfer agent (MTA) used on Unix-like operating systems. The first version was written in 1995 by Philip Hazel for use in the University of Cambridge Computing Service's e-mail systems. There is currently a port of Exim to Microsoft Windows using the Cygwin emulation layer.

[edit] Logging Outputs

Below are logging outputs of this software. These examples should be detected by Fail2ban. Please remove any confidential information before saving this page. Change IP addresses to 192.0.2.0/24.

If the offending host is not trivially visible in the logging output, please give more detailed information.

[edit] Failregex

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.
