Email configuration
There are two email servers set up in the department.
- Vayu (10.101.1.1) - Faculty mail server.
- Shakti (10.101.1.2) - Student mail server.
Email server is configured using [http://cr.yp.to/qmail.html qmail].
Vayu and Shakti run both email servers. Email servers are run at the boot time using [http://cr.yp.to/daemontools.html daemontools]. These tools are installed under /command. The service scanner svscanboot is started from /etc/inittab; it keeps scanning services configured under /service. Any service found in /service is automatically started.
To manage the services started from /service, use qmailctl command.
