Ok thank you for the info, this did scare me :). Its taxing my small system.

      Have you considered running something like fail2ban on the
system? It would temporarily (you set the time) block said IP at the
firewall, which usually make them look for easier pickings.

You've set "notify_classes" to send you too much email.

Session aborted, reason: too many errors


Not much of an attack, just an open-relay test.  Just ignore it,
and ideally arrange to not be notified about it.

Any specific suggestions to close such attack?
