Frequently getting this warning in daily mail report.
smtpd (total: 84)
84 unknown[122.228.x.x]: SASL LOGIN authentication failed: aut...'
What does this indicate? We have a small implementation of ZCS OSE 8.0.2 with few users.
It means exactly what it says, a 'user' tried to login from that IP address and it failed.

You could block the IP on your firewall.
I think this is the easiest solution.
Thanks for the reply.
