Getting an error in Event Log...
EventID: 1021
Source: MSExchangeTransport
Task Category: SmtpReceive
Receive connector XXXXXXXXXX rejected an incoming connection from IP address xxx.xxx.xxx.xxx. The maximum number of connections per source (20) for this connector has been reached by this source IP Address.
The following are the current values for the Outbound and Inbound Connections:
MaxOutboundConnections: 1000
MaxPerDomainOutboundConnections: 500 (was previously set to 20 until I changed to 500)
MaxInboundConnection: 5000
MaxInboundConnectionPerSource: Unlimited
MaxInboundConnectionPercentagePerSource: 100
Based on these values, I cannot understand how I am still getting an error indicating the maximum number of connections per source (20) has been reached. The services were all restarted and the server even rebooted yet the errors persist? How is
this possible?
