When I try to submit a vulnerability report following the instructions at https://www.ptc.com/en/documents/security/coordinated-vulnerability-disclosure, sending an email to email@example.com, I'm getting a reply from firstname.lastname@example.org saying only senders of the same organization are allowed to use the email@example.com email address (see attached screenshot). What am I supposed to do to submit my report? Thanks.
PS: I don't think "Quality Mgmt" is the right label for this topic but there wasn't any other fitting better.
Thank you for the hint but I'm a security researcher and my client is using windchill. I'm not a customer and do not have the required privilege level (actually I registered as a student).
