I'm trying to trace an attachment within an SIS subdirectory to the
email message(s) that link to it. I say messages because I'm also
using dovecot dedup. My understanding is the linked file name is the
hash value of the attachments contents concatenated with the GUID of
the email message. I have had marginal success with a message I
created myself.
Example: I generated an email with two attachments. Here are the
links in my attachment directory.

I keep experimenting with this and I still haven't found a reliable
way to track an attachment back to it's original message so I can
either notify the user or delete the message with doveadm. Is this not
possible? I'm using mdbox if that matters. I see a similar thread
going right now about virus scanning and deleting messages but that is
maildir and I suspect not using SIS for attachments.
The very few times I've needed to trace a SIS attachment to a mailbox, I
just grep the "storage" folders for the file hash
find username/storage -type f -exec grep
