Mailversand Problem

Hallo,

ich habe Probleme mit dem Mailversand an manche Adressen.

Ich erhalte folgende Meldung:

Quote

<email@emailempfänger.de>: host mailgate.de[X.X.X.X] said: 553 Access denied: 553 (V4.4-RULE-1111) We and also big providers as AOL do not accept mail from systems with an GENERIC PTR. We recommend you should use your provider's mailserver as SMARTHOST. To have an exception made for [email protected], contact us using the form on our Website or give us a phonecall. (in reply to RCPT TO command)

Reserve DNS sind natürlich angelegt, dass Problem tritt nicht bei allen Emailsadressen auf. Mailversand an web.de funktioniert zum Beispiel problemlos.

Hat jemand eine Idee?

Danke.

Grüße

Hallo, danke für eure Hilfe.

Mein PTR lautet:
server1.domain.tld

Die Absenderemail lautet [email protected]

Die Auflösung funktioniert tadellos.

Sender Policy Framework (SPF) is an email validation
system designed to prevent email spam by detecting email spoofing, a
common vulnerability, by verifying sender IP addresses.

You do not have a SPF record, please add the following one to your domain xxx.de:

v=spf1 a mx ip4:x.x.x.x ~all

Reverse DNS lookup or reverse DNS resolution
(rDNS) is the determination of a domain name that is associated with a
given IP address.
Some companies such as AOL will reject any message sent from a server without rDNS, so you must ensure that you have one.
You cannot associate more than one domain name with a single IP address.

Here are the tested values for this check:
IP: x.x.x.x
HELO: server1.xxx.de
rDNS: server1.xxx.de

Wie lege ich den den MX Eintrag korrekt an?

Ok, habe das mal angelegt.
Allerdings noch die selben Fehlermeldungen beim Mail-Check.

Sieht jetzt so aus:

Quote

name=server1.xxx.de
value=server1.xxx.de
ttl=10800
priority=10
type=MX
