=head1 SYNOPSIS
|
||
|
|
|
||
|
|
This plugin checks the badmailfrom_patterns config. This allows
|
||
|
|
special patterns to be denied (e.g. FQDN-VERP, percent hack, bangs,
|
||
|
|
double ats).
|
||
|
|
|
||
|
|
=head1 CONFIG
|
||
|
|
|
||
|
|
Configuration is placed in the following file:
|
||
|
|
|
||
|
|
F<config/badmailfrom_patterns>
|
||
|
|
|
||
|
|
Patterns are stored in the format pattern\sresponse, where pattern
|
||
|
|
is a Perl pattern expression. Don't forget to anchor the pattern
|
||
|
|
(front ^ and back $) if you want to restrict it from matching
|
||
|
|
anywhere in the string.
