I am getting the following warning in my exchange 2013 error logs:
Receive connector Internet Connector HFC-EKHAT rejected an incoming
connection from IP address 1xx.2xx.1xx.1xx.
The maximum number of connections per source (20)
for this connector has been reached by this source IP address.
This appears constantly in the logs. This is incoming from a country that we don't usually send or receive mails from often.
Is this normal or could this point to something more sinister?
