(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
