Hi,

My setup is:

mail_attachment_dir = /var/mail/attachments
mail_attachment_hash = %{sha512}
mail_attachment_min_size = 64k
mail_attachment_fs = sis posix

Something works - but I expected that is one instance of file, and this file is linked to messages. But here in folder I have got this:

sudo ls -la /var/mail/attachments/8b/67/
