Hi, In a similar situation, the reason was Outlook - account using IMAP, deleting the emails by the most important client, without any rules or Junk filters.
I would suggest before anything else: - Create "recipient bcc copy" (like "forward a copy to another mailbox"). You can compare both mailboxes if needed; - Use the mailbox only by webmail temporary if possible, for the test period; - Of course, enable the logging...
