The port number can be changed in the mail server. If you change the port number in the mail server, also change the port number registered in this software. (The default port number is 465.) For details, see the following.
*1 The default value. Can be changed when installing this software. Can also be changed in the configuration file of this software.
*2 The default value. Follows the settings of the database server.
*3 Use a free port. The port number cannot be fixedly set. The Agent waits to receive UDP packets with this port, and instructs the printer to send a SNMP response to this port.
