SmtpReceive could not start listening on a configured binding because the specified address is already in use.

This Error event indicates that the specified combination of IP address and port number is being used by another process on the server.

Each Receive connector on a Microsoft Exchange Server 2007 Hub Transport server or Edge Transport server must use a unique combination of IP addresses and port numbers to listen for inbound connections from remote SMTP messaging servers.

If other SMTP messaging services are running on this server, they may be using an IP address and port number combination that conflicts with an existing Receive connector. For example, the default Receive connector on an Edge Transport server is configured to use 0.0.0.0:25. The default Receive connectors on a Hub Transport server are configured to use 0.0.0.0:25 and 0.0.0.0:587.

To resolve this error do one or more of the following:

  • Remove or relocate any other SMTP messaging services that are running on this server.

  • Configure any other SMTP messaging services that must run on this Hub Transport server or Edge Transport server to use an IP address and port number combination that doesn't conflict with any Receive connectors that are configured on the server.

  • Configure the Receive connectors on this Hub Transport server or Edge Transport server to use an IP address and port number combination that doesn't conflict with any other SMTP messaging services that must run on this server.

For more information, see Receive Connectors.
