Hi,
sis attachment deduplication is broken in 2.2.16 upwards. It is caused by this commit. https://github.com/dovecot/core/commit/664bf3e236c214aee86294483c379e4fa66c2...
in src/lib-fs/fs-sis.c function fs_sis_try_link() is comparation of inodes of hash files. Because fs_stat() after that commit use fstat() on open fd of temporary file instead of stat on filename. But that temporary file has differnt inode.
It not cause any corruption but it will not save any space. Because every duplicate attachment will be in separate file.
