Resolve email bounce, PTR and DNS errors

Hello. The job is quick: fix the PTR and DNS registers in a CWP Panel server so the emails will not bounce. If you do not have true experience with DNS records, do not bid. Any wrong configuration will result in loss of business for us and we will go after reimbursement of losses. I prefer to be frank in order to receive bids only from skilled professionals. You will work in the server through TeamViewer.
