Unsure on how to fix PTR

mv flag

I am trying to setup a custom email for a company website. The only issue is that when sending an email to a gmail account, I get the following back:

The mail system : host gmail-smtp-in.l.google.com said:
The IP address sending this message does not have a PTR record setup, or the corresponding forward DNS entry does not point to the sending IP. As a policy, Gmail does not accept messages from IPs with missing PTR records. Please visit https://support.google.com/mail/answer/81126#ip-practices for more information.

I have my records on Cloudflare as seen here: Image of DNS records on Cloudflare

On Linode which is hosting my VPS, I have the rDNS as seen here: Image of rDNS on Linode

I used an email checker mail-tester.com to check my email [email protected]. It returned the following: Image of mail-tester output I don't quite understand what the issue is as I have never done this before.

Your PTR and HELO mismatch. Just fix your HELO or point the PRT accordingly.

It appears that your email server is sending example.com in the HELO command rather than mail.example.com. You need to change this in the configuration of your email software.

I didn't setup the software. I ran this script: https://github.com/LukeSmithxyz/emailwiz So I don't really know how I would go about editing that.

The forward and reverse record must match. E.g. `mail.example.com` *must* point to your ip, and the PTR for your IP *must* point to `mail.example.com`

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
