I guess you have "mail_attachment_fs = sis posix" (default)? Sounds like
there could be a bug where SIS does comparison of files but for some
reason thinks they are different.

You could try if you can merge them with:

mkdir /tmp/queue
touch /tmp/queue/6e2df299fa96daec9b4735d07c494046429be4d6-foo
doveadm sis deduplicate /var/attachments /tmp/queue
