DMARC error messages

Whenever I send an email most of the time they get rejected and sent back with the following " remote server returned 550 5.7.509 access denied, sending domain comcast.net does not pass DMARC verification and has a DMARC policy of reject. Can anybody assist me with what to do about this issue. Or is it an issue with comcast.net? Things that I've had this email address for approximately 30 years maybe? I do not want to have to change it and change all my contacts and update them.

How are you sending the emails?  

I assume you can send emails through the xfinity webmail page. Using their webmail or their SMTP server should work.  However, if you are using someone else's server, it should not work.
