Stop Email Sending

Hi, we have a specific WordPress setup in a secure self-hosted environment so the WP_CONTENT directory doesn’t match up with your security rules for attachments.

Is there a way to allow uploads from a different directory or is there a way I can stop an email being sent so I can send my own email with the attachment? Using the wpcf7_before_send_mail hook. I’ve got it working to send a second email with the attachment but would like the one email

I would prefer the last option
