        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::> <mailto: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::>
        <mailto: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::> <mailto: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
