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.
All the mails for aero domain comes to shakti first and then diverted to vayu if its destined for it. Mail aliases forward all the mails either to vayu or smtp.iitb.ac.in. In vayu, outgoing mails goes to smtp.iitb.ac.in only. In shakti, outgoing mails goes to smtp.iitb.ac.in or vayu.
