I use your system for years, but spam is something i would like to avoid.
My questions:
(1) nshzfsi@cgv.org —> this came in Inbox. (But this address does not exist) -> does not greylisting rule these mails out ?
(2) Received: from example.com (mail.example.com [127.0.0.1]) —> is this normal that localhost or 127 ip address is there ?
(3) Received from where does this come from ? is this normal ?
