||Configuring sendmail on Jaguar|
|Subject:||What is purpose of 2nd sendmail session?|
Modern versions of sendmail like the one in OS X separate the handling of mail coming in and mail originating here to go out. The first line starting up sendmail is the one that listens on port 25 for incoming mail and handles it. The second line starting up sendmail with a different configuration file waits for messages originated on the Mac and sends them out. Because of the "q1h" argument, both of these run as daemons and process the queue once every hour. The first one uses /var/spool/mqueue as its queue directory; the second uses /var/spool/clientmqueue.
