I run a small company and we have feedback from some of our customers that when they attempt to email us the email is immediately rejected with the following error:
This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address failed:
domain has no valid mail exchangers
This was happening infrequently at first but is now becoming more common, most email seems to work fine (the registration for this site for example) and it is OK to send email out.
These are the settings from the domain name registration page (I only add these as I have found some reference online to this being the issue in another case, but I am not sure why)
DNS TYPE PRIORITY DESTINATION/TARGET ENTRY @ MX 10 mail.everfurniture.com @ A 22.214.171.124 ftp CNAME ftp.myserverworld.net mail CNAME mail.myserverworld.net www A 126.96.36.199
Any help or guidance to what to look for is much appreciated!
