Ahoj,
mám v postfixu nastaveno SPF a taky reject_unknown_sender_domain, přesto mi procházejí spamy z takovýchto domén:
(DMARCIAN spf check):
tatiltivi.com
v=spf1 a mx ip4:193.17.5.0/24 ~all
1 +a:tatiltivi.com:194.146.50.34/32
1 +mx:tatiltivi.com
Warning! Void lookup: no records found for "tatiltivi.com MX" while evaluating "mx".
Chápu to pravidlo v main.cf špatně ?
Postfix mail_version = 2.7.1
Dle postfix.org:
reject_unknown_sender_domain
Reject the request when Postfix is not final destination for the sender address, and the MAIL FROM domain has 1) no DNS MX and no DNS A record, or 2) a malformed MX record such as a record with a zero-length MX hostname (Postfix version 2.3 and later).
