Hallo
Wo kann man im MailGW eingehende Mail checken ob der RDNS Eintrag der Gegenseite stimmt?
Danke
Gruss Andi
 
Kommt darauf an, was genau mit der Frage gemeint ist/was das ueberpruefen bewirken soll

Ich nehme mal an Du meinst die Optionen "Reject Unknown Clients" und "Reject Unknown Senders" - siehe punkt 4.7.4 unter
https://pmg.proxmox.com/pmg-docs/pmg-admin-guide.html#_mail_proxy_configuration

(die setzen die postfix optionen reject_unknown_client_hostname bzw. reject_unknown_sender_domain in der smtpd_sender_restrictions liste der postfix config:
http://www.postfix.org/ADDRESS_VERIFICATION_README.html
http://www.postfix.org/postconf.5.html#reject_unknown_sender_domain)

Ich hoffe das hilft!
