Hi,
I would like to avoid any interference of any end user in an existing ticket. Specially Malformed Emails such as Mailer daemon.
How to avoid such behavior?
OST Version: 1.17.2
PHP Version: 8.0
I saw an option under Admin=>Emails=>Settings=>Incoming email section.
Accept Email Collaborators:
Should I uncheck that option?

Please share your thoughts.
Thanks
