Is this issue on my end or their (the receivers) end? How should I fix this problem?

1) Login to the Mailgun control panel and select the Domains section. 2) Select any domain that is in the orange “unverified” state. 3) In the Domain Verification & DNS section, locate the records with the red warning indicator.
You need to add the following MX records to your DNS and associate them with the subdomain mg.yourdomain.com
mxa.mailgun.org 10
mxb.mailgun.org 10
Likely you are seeing those errors because certain email servers do an MX lookup on the domain of the sender of the email (in this case mg.yourdomain.com). If those MX records do not exist, the server will reject the mail.
You likely set up an MX record for your domain but not the subdomain from which the email is being sent. You need to set up an MX record for the subdomain also.
