Problem: Some iNEWS users cannot receive emails with the iNEWS internal mail system.
Components and Reasons: The iNews mails are processed from the Linux Sendmail server on one of the iNEWS machines. The iNEWS mailserver resource specifies which machine (A or B) is responsible for this task. Run
INEWS-A# list c mail DEV DEVICE_TYPE COMPUTER NOTIFY OPTIONS DEVNAME S111 mailserver A 111
to get the information.
The Sendmail program of course needs the users to know. iNEWS users are not Linux users on the server machines. To workaround this problem in the file /site/.mail/aliases is a list of all iNEWS users which can be taken then by the Sendmail program.
This aliases file is the almost reason for iNEWS mail problems. It is created and updated automatically during each groupchecker run.
But the groupchecker process runs not necessarily on the same machine as the mailserver. Therefore during an update the mail aliases file is automatically transfered to the other iNEWS server. This is done via rpc.
Finally the information about new mails is sent to the users iNEWS client session (in case she is logged in…) If a local firewall blocks those incoming packets on the client machine the user'll not get informed.
