[Postfixbuch-users] wieso greylisted?

[Olaf Zaplinski]

Hallo,

ich frage mich, wieso manche Hosts greylisted sind. Ein

cat mail.log|grep grey

spuckt z.B.

delayed 310 seconds: client=moutng.kundenserver.de

aus. Aber

echo moutng.kundenserver.de | postmap -fq - regexp:greylisted.regexp

bringt kein Ergebnis. Wieso also wurde dieser Host per Greylisting gesperrt?



Die Konfig dazu:


smtpd_restriction_classes =
         verify_sender
         greylisting

verify_sender = reject_unverified_sender
greylisting = check_policy_service inet:127.0.0.1:9998


smtpd_recipient_restrictions =
         permit_mynetworks
         permit_sasl_authenticated
         reject_unknown_sender_domain
         reject_non_fqdn_sender
         reject_non_fqdn_recipient
         reject_unknown_recipient_domain
         reject_unauth_destination

         check_recipient_access btree:/etc/postfix/check_recipient

         reject_rbl_client zen.spamhaus.org
         reject_rbl_client dnsbl.njabl.org
         reject_rhsbl_sender bogusmx.rfc-ignorant.org
         check_client_access regexp:/etc/postfix/greylisted.regexp
         reject_rbl_client bl.spamcop.net
