Greetings community, I have a challenging issue that seems to circle around DNS, the lookup of the MX IP address under the domain baylandtransport(dot)com
There are several returned (bounced) emails from multiple mail servers. The staff at (baylandtransport(dot)com) are sending out emails to various email addresses throughout the day.
Here is the info returned in the bounced email:
unable to get mx info: failed to get IPs from PTR record: lookup : unrecognized address
After doing research I have found to the following which points back to Cloudflare, the DNS for this domain is hosted on Cloudflare and has been for over 6 months. I understand how robust and reliable the Cloudflare network is, problems can occur and this is my attempt to reduce them.
The reason you will see error: unable to get mx info: failed to get IPs from PTR record: lookup : unrecognized address is that when attempting to deliver the message, the servers are not seeing that there is a valid MX record or A record that exists on the domain. (baylandtransport(dot)com)
The MX record will handle receiving incoming messages, however per RFC, if an MX record does not exist we will use the IP address, which would be located on the A record of the domain.
Terminal domain lookups
- $ dig +short TXT baylandtransport(dot)com
- $ dig +short MX baylandtransport(dot)com
I have been using the following service to dig deeper
Thank you for your attention!
