PMG 7.8.3 - SpamAssassin AskDNS Modul Problem

Feb 4, 2021
Wir wollen das Spamassassin Plugin "AskDNS" einsetzen, um den MX-Record der Domain im "Reply-To"-Header prüfen, falls diese gesetzt wurde.

Im Quelltext der findet sich folgender Hinweis:
Special supported tag HEADER() can be used to query any header content, using same header names/modifiers that as header rules support.
For example _HEADER(Reply-To:addr:domain)_ can be used to query the trimmed domain part of Reply-To address. See Mail::SpamAssassin::Conf documentation about header rules.

Wir nutzen folgende Regel in der

ifplugin Mail::SpamAssassin::Plugin::AskDNS
add_header all AskDNS loaded
# Block MX hosts of domains listed in Reply-To
askdns          LOCAL_REPLYTOMX _HEADER(Reply-To:addr:domain)_ MX /
describe        LOCAL_REPLYTOMX Block list of MX hosts looked up from Reply-To
score           LOCAL_REPLYTOMX 1.0
endif # Mail::SpamAssassin::Plugin::AskDNS

Im Log des DNS-Servers ist ersichtlich, dass AskDNS keinen MX-Lookup für die Reply-To-Domain durchführt.
EIne Debugausgabe vom Spamassassin zeigt, dass das AskDNS Plugin zuvor geladen wurde.

Andere selbstgebaute Regeln in der funktionieren ohne Probleme.
