On July 5, I made some changes to my DNS settings to satisfy cPanel's Email Deliverability standards, and since then my List Serve no longer works.  I don't know if that was the cause, or if I have done something else to break it, and DNS records were just a coincidence.

These are PHP messages that seem to relate to a WordPress plugin.  Nothing to 
do with Mailman, which is written in Python.

Your problems sound like a problem with the Mailman => outbound mail server 
interface -- something is misconfigured there.  Do you know what you are using 
for a mail server? Sendmail? Postfix? Something else?  What operating system 
is the server itself running? CentOS 6, 7? Ubuntu? Something else?
