Hi,

Many thanks for your reply. It's a *very important* addition actually.

There is lack of documentation on SIS. So I have done some experimenting and found out that the command
# doveadm purge -u johndoe
*is mandatory*. Without this step attachements will stay in mail_attachment_dir forever.

Man doveadm-purge(1) states "doveadm-purge - Remove messages with refcount=0 from mdbox files", but actually it also removes attachments from mail_attachment_dir.
