I have a website setup on a hosting provider and now when any mails are sent from it, they go to spam in gmail (from field looks like this: contact@mydomain.com via webserver.offshore-hosting-service.com).

So i used mail-tester.com to test and I received a score of 7.7/10.

A few things still needed fixing:

1) rDNS: Delivered to internal network by a host with no rDNS This may be a false-positive, please check the reverse DNS test below to confirm or not this issue

2) DKIM: Your message is not signed with DKIM

3) DMARC: You do not have a DMARC record

So I did the following (data has been obscured):

1) I created a PTR DNS entry for rDNS like this):

30.61.2.94.in-addr.arpa PTR mydomain.com

2) DKIM:

Could someone help me figure out how to do this?

3) DMARC:

_dmarc.mydomain.com TXT "v=DMARC1; p=none"

After a day, I ran another mail-tester test and still got the same issues. What have I done wrong?

The one part I cannot figure out even after googling is how to setup the DKIM. Can someone help me here?

DKIM setup is quite simple Follow the below steps -

  1. First step is to create a SSH keypair. For Windows you can use PUTTYGen and for Linux and Mac, you can use ssh-keygen, See this for details on how to generate

  2. Placing the public key as a TXT record for your domain in the DNS settings, depending on your DNS provider the steps of placing a TXT record may vary.

  3. Generating and saving the signature, so that it can be used while sending mails in the headers.

  4. Validate the DKIM.

Follow this article for detailed link on each step.
