So I was thinking that there probably could be some tool that during a
user's backup it would write the attachments among the user's other
files, so it would be easy to find all of the files needed for a
restore. This would of course mean that backups can take a lot more
space, because there's no SIS. Perhaps there could be some other
I see.
Instead of writing the links directly to the filesystem, why not keep a
links list (not a linked list 8-)) file in each directory that contains
the information for the links that should be there (source, dest,
attributes), then add an inotify hook in Dovecot to create/update/delete
the hard links in the directory so they match the links list?
The links list would only need to be opened when there's a change and
could remain closed (and backup-able) at all other times, and restoring
a links list would immediately trigger the inotify hook and regenerate
all the required links.

Sorry for joining late this thread, but this is a very important issue
for us.
Terry's solution feels great: just a little modification of the mdbox,
adding a ¿text? file with the list of attachment files, that is modified
every time an attachment is added/deleted.
With that, it seems quite easy to modify our mailbox recovery script to
something like:
- recover the mailbox as now
- recover every attachment file that file points to.
Other option: a new doveadm option that could generate this list, and
then recover the mailbox, generate the list, recover the attachments.
Also: no change needed to the backup process itself, and that's good news.
