=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 $) if you want to restrict it from matching
|
|
anywhere in the string.
|
|
|
|
^streamsendbouncer@.*\.mailengine1\.com$ Your right-hand side VERP doesn't fool me
|
|
^return.*@.*\.pidplate\.biz$ I don' want it regardless of subdomain
|
|
^admin.*\.ppoonn400\.com$
