+=head1 SYNOPSIS |
| 23 |
+ |
| 24 |
+This plugin checks the badmailfrom_patterns config. This allows |
| 25 |
+special patterns to be denied (e.g. FQDN-VERP, percent hack, bangs, |
| 26 |
+double ats). |
| 27 |
+ |
| 28 |
+=head1 CONFIG |
| 29 |
+ |
| 30 |
+Configuration is placed in the following file: |
| 31 |
+ |
| 32 |
+F<config/badmailfrom_patterns> |
| 33 |
+ |
| 34 |
+Patterns are stored in the format pattern\sresponse, where pattern |
| 35 |
+is a Perl pattern expression. Don't forget to anchor the pattern |
| 36 |
+(front ^ and back $) if you want to restrict it from matching |
| 37 |
+anywhere in the string. |
| 38 |
+ |
| 39 |
+ ^streamsendbouncer@.*\.mailengine1\.com$ Your right-hand side VERP doesn't fool me |
| 40 |
+ ^return.*@.*\.pidplate\.biz$ I don' want it regardless of subdomain |
| 41 |
+ ^admin.*\.ppoonn400\.com$ |
