Hi Jayson Who was the domain "complaining" about this? You did not mention.
We recently had the problem that German provider "1&1 Internet" (who also operates one of the biggest freemail services, GMX, and some other mail domains) would not accept mails from our domain (and also not send to it), throwing an error message about some missing MX record. However, all other domains (or addresses) could be reached without any problems, and they could also send mails to us. Please check on the site of GMX <https://postmaster.gmx.com/en/error-messages> what the requirements are for them to accept mail messages. Then you can check your DNS entries using <https://intodns.com/> whether all necessary entries are there. Christian > Jayson Smith <mailto:jayb...@bluegrasspals.com> > 22.
