=head1 SYNOPSIS
|
||
|
|
|
||
|
|
This plugin checks the badrcptto_patterns config. This allows
|
||
|
|
special patterns to be denied (e.g. percent hack, bangs,
|
||
|
|
double ats).
|
||
|
|
|
||
|
|
=head1 CONFIG
|
||
|
|
|
||
|
|
config/badrcptto_patterns
|
||
|
|
|
||
|
|
Patterns are stored in the format pattern\sresponse, where pattern
|
||
|
|
is a Perl pattern expression. Don't forget to anchor the pattern if
|
||
|
|
you want to restrict it from matching anywhere in the string.
|
||
|
|
|
||
|
|
qpsmtpd already ensures that the address contains an @, with something
|
||
|
|
to the left and right of the @.
