I am having a problem receiving some emails. Specifically from firstname.lastname@example.org I get my kids' sports information from this domain. My husband is a coach and when sending me an email from the site, he doesn't get any return error, but I don't receive it anymore. He also has a comcast email address, to which they are delivered succesfully. I was receiving emails from here for several years. I believe I stopped receiving them in mid-December 2019. They are not in my SPAM folder either, I actually recently tried disabling this all together, just in case. But it doesn't seem to help.

i've reviewed this issue and the email email@example.com has not attempted delivery to @jenj1105 . This is something the sending side would want to review and see if the email is saved incorrectly in their database or if they receive a bounceback from their internal server.
