    Subject: <> in MAIL FROM:
    Message-Id: <1536961802@winserver.org>

    So I am getting this from wcSMTP when my inbound mail scanner goes to
    deliver some mails:

    20180914 16:09:03 (09D8) MAIL: Unknown local domain user in return path: double-bounce@winserver.org
    20180914 16:09:03 (08C8) EHLO: Incoming connection:
    inbound.winserver.org []
    20180914 16:09:03 (08C8) MAIL FROM: <>... Sender ok.

    How do I fix this and keep this from happening? I use the eFa appliance
    to filter inbound emails before it hits my WINServer system.
