SOLVED OP address used for HELO

[papazetis]

Hello.

How can I fix the smtp banner to contain the Hostname and not my IP Address.

I am using WHM 62.0 (build 16) and Roundcube for sending my emails.

Hello,

Do you have a valid rDNS setup on the IP?

You can check using dig in SSH:

# dig -x 172.217.8.174 +short

Replace with your IP.

If it is, its possible you have the following option checked in WHM > Exim Configuration

Reference /etc/mailhelo for outgoing SMTP HELO

If yes, go into /etc/mailhelo and make sure its set up properly like so:

*: server.hostname.com

or whatever is set as your rDNS

 

[papazetis]

Yes I have setup rDNS correctly.

My hostname is set to the the same I get from "dig -x".

Exim Configuration is like this


And I change /etc/mailhelo to my server rDNS but I am still getting the same error

 

[Jcats]

Most likely a false positive then, as long as your server hostname is setup properly along with the rDNS, I don't see why you would be having this problem.

Can you send yourself a test email and check the headers of the email then check the HELO manually, does it show an IP?

 

[papazetis]

Yes it shows my server's IP in HELO

Hello,

Could you verify if the issue persists when temporarily disabling the "Introduce a delay into the SMTP transaction for unknown hosts and messages detected as spam" option in "WHM >> Service Configuration >> Exim Configuration Manager >> Basic Editor"? I've seen reports that this option prevents third-party utilities such as MXToolBox from completing a check of the RDNS entry.

Thank you.

Thank you for your support.
I just fix it.
The problem was with RoundCube. I change the $config['smtp_helo_host'] to point to my rDNS.
