Parameter Dispatcher option

The interpretation and allowed values for the  Dispatcher   option are service specific. In the case of an SMTP service, the   option may be set to   ,  to associate a default  TCP/IP channel with the port for that  SMTP service. (Note that the presence of the equal sign within the value means that when using , the value will need to be quoted.) For example, the   service sets   to  " " so that incoming mail submissions are handled on that channel. msconfig&#x3e; show service:SMTP_SUBMIT.parameter role.dispatcher.service:SMTP_SUBMIT.parameter = CHANNEL=tcp_submit Note that using  to set a channel name can be useful if you wish to run SMTP servers on multiple ports---perhaps because your internal POP and IMAP clients have been configured to use a port such as the submission port 587 rather than port 25, thus separating their message traffic from incoming SMTP messages from external SMTP hosts---and if you wish to associate different TCP/IP channels with the different port numbers.
