Last Friday rolled a new connection. Update DNS for all my ip addresses Friday. Did the ISP create a PTR record for this for the mail server at approximately 12:00 CST on Monday?

So I check again and tell mxtoolbox it’s ok and then to whatsmydns.net and again it says my A records are very but good, checking the PTR records tells people they have an invalid IP address.
All I can think of is that the PTR document was added through my ISP. I’m assuming the DNS is a server, separate and I control all the records in my house on with GoDaddy, so perhaps their integrated PTR record that matches a specific subdomain of my domain is not only valid?< /p>
Do I need a PTR record?
You need a PTR record because many mail servers will probably reject emails from a mail server that has absolutely nothing to do with it. After that, the goal is to keep spam out of your inbox.

What is the PTR record?

The entry is the ptr of a direct DNS or domain name server. PTR stands for Pointer To and is a fixed component of mail systems. servers. In the DNS case, domains refer to their respective IP addresses. But in a pocket PTR, the opposite is true, i.e. The IP addresses are associated with their respective domains. These entries help ensure that the server contains the IP address that caused the connection. This is an important security protocol followed by both server-to-server emails and emails from dedicated servers.
When a sender sends an important email, it goes through the MX, then through the recipient’s MX, before finally being delivered to the recipient. If at any level you get a fantastic PTR error, you will get error 554 “Invalid PTR Record Error” with things like this:
Messaging service not found 554-No service 554-Invalid smtp DNS PTR location record.
What causes the PTR error besides fixing it?
The sender has recently migrated to a new RDNS processing data center and is not yet configured.
The device sending emails has a new IP address but no PTR records. Returns
occurs in network latency, which in turn causes the lookup to failand DNS
In any of the above cases, this error can be caused by:
The servers were unable to double-check the PTR records because there were very few of them initially. web hosts do not typically install PTR records for assigned IP addresses after a server migration. Because our PTR is missing, the mail servers treat your entire IP address as spam and therefore filter the transmission. Solve this problem, just add them by ptr entry.
But to be sure, let’s check if the anomaly exists or ptr doesn’t exist. This is to use the following code:
This will display those RDNS entries. If not, you may need to get the correct PTR records for your IP address. Your mail server provider will get the records. If an external DNS server is used, it is often necessary to add PTR records.
If the area code above confirms that there are PTR documents for your IP address and you can’t send an email, the ptr is probably invalid.
The general trend that we have gainedWhat we find with most hosting providers is that they assign each IP address a generic for-ptr that looks like this: “xxx-xxx-xxx-xxx-host.provider.tld”. then while p>
But this is you making it generic for each IP address, non-mail machines will see it as spam because people think it will be a dynamic IP address.
To resolve this jurisdictional issue, you need to change our PTR from Generic to (Fully Essential FQDN with FQDN One). For example, abc.nameofyourreserver.com.
If it is a virtual private server that hosts two or more domains on the same Internet address, you can only select one server hostname and its name as the ptr entry.
