    I have checked out authentication with my submission port 587 and
    I must authenticate before sending. However, I have entries in the
    log from a “bad guy IP address” which say “sender accepted” and
    its giving me heartburn.

    2019-12-10 02:43:04.376530500 CHKUSER accepted sender: from
    <someb...@somewhere.net::> remote <4vFoWf3:unknown:64.225.41.10>
    rcpt <> : sender accepted

    2019-12-10 03:04:09.269688500 CHKUSER accepted sender: from
    <anotherb...@somewhere.net::> remote
    <3aJfz4D7:unknown:64.225.41.10> rcpt <> : sender accepted

    (Note: the IP 64.255.41.10 is the real IP of the bad guy)

    There are no corresponding lines which say, “client allowed to relay”

    Note after the from address, there are two colons:
    <someb...@irtc.net::> . On all legitimate entries, there are no
    such double colons.

    How did this guy get that entry into my submission logs without
    authenticating?  Is this something I need to worry about?

    Any input would be really appreciated
