We Sincerely Apologize For The Inconvenience
During the past three years, Palm Beach Cuisine has experienced issues sending mail to Comcast subscribers. We receive bounce-back messages such as Failed Recipient: firstname.lastname@example.org Reason: Remote host said: 554 Comcast requires that all mail servers must have a PTR record with a valid Reverse DNS entry. Currently, your mail server does not fill that requirement.
A Pointer (PTR) Record, also referred to as a Reverse DNS record, resolves an IP address to a fully-qualified domain name (FQDN) such as PalmBeachCuisine.com. Not having a PTR would create chaos and shut down a mail server because all mail sent would not be accepted at any destination server.
Of course, Palm Beach Cuisine, Inc utilizes dedicated servers and follows all security protocols and employs all necessary records. If not, mail sent to Gmail.com, Aol.com, Yahoo.com, Outlook.com and many other ISP's would bounce back never reaching the destination inbox, and it does not. Not all Comcast mail bounces. Some subscribers receive mail sporadically, and other subscribers do not. It appears this issue is only affecting a portion of the servers Comcast is using, but, since we cannot determine which ones, we must be proactive in preventing further frustration among our client's subscribers and our own.
We again apologize for the inconvenience, but until Comcast addresses this issue, we will no longer be accepting Comcast mail addresses on behalf of the clients we send mail for nor Palm Beach Cuisine Inc. We hope you might consider signing up for a free Yahoo.com, Gmail.com, Aol.com account or another free email service so we can send you quality dining incentives throughout the year.
