Resolved Mail Test failed

[Ankebut]

when i am Testing my Email Spam Test Result receive always error below and i dont know what can you do to fix the probelm, can any help please?

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.


Your IP address 148.251.246.48 is associated with the domain mail.doitauto.de.
Nevertheless your message appears to be sent from industriemeister.io.

You may want to publish a pointer (PTR type) DNS record with a value of industriemeister.io or use mail.doitauto.de as hostname in your mail software



Here are the tested values for this check:

• IP: 148.251.246.48
• HELO: industriemeister.io
• rDNS: mail.doitauto.de

Hi Ankebut,

Nevertheless your message appears to be sent from industriemeister.io.

Which is absolutely correct, if you setup:

=> Home > Tools & Settings > Mail Settings

=> Option: Outgoing mail mode

Send from domain IP addresses and use domain names in SMTP greeting

The suggestion:

You may want to publish a pointer (PTR type) DNS record with a value of industriemeister.io or use mail.doitauto.de as hostname in your mail software

... didn't check your actual DNS - entries, which are absolutely setup correctly with:

industriemeister.io. A 3600 148.251.246.48

and

industriemeister.io.    TXT    3600    "v=spf1 +a +mx +a:mail.doitauto.de -all"

( I would just add the TRUSTED IPs as ... i.e.: ip4:148.251.246.48 , as the reverse check of your IP only displays: mail.doitauto.de )

...
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.

Such a statement is quite misleading, as it declares a misconfiguration in setup, which is NOT the case.

All should be fine and even AOL will exept your eMails - just test it and reply with ( possible ) error messages from your mail.log and the corresponding header from your eMail.

I already had that

Send from domain IP addresses and use domain names in SMTP greeting

you mean i changes the

v=spf1 +a +mx +a:mail.doitauto.de -all

too

v=spf1 a mx mx:mail.doitauto.de ip4:ip4:148.251.246.48 ~all

DNS show follow

Hi Ankebut,

NO!. Sorry. You misconfigured the suggestion!

Correct would be:

v=spf1 +a +mx +a:mail.doitauto.de ip4:148.251.246.48 ~all

You need to open your Domain hoster customer panel and edit domain ip and reverseDNS for the IP 81.46.243.2.
