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.

(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: <[email protected]::> . 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
