IIT Kanpur has open source installation of mailing system.
the mail servers can be accessed via mail clients such as Thunderbird, KMail, MS Outlook etc. or via web mail interface.
Stored mails on the server can be accesses via POP3(S) or IMAP(S) protocol.
Usually POP3 is used if you have a slow connection (i.e. residing outside in an remote place which has very slow Internet).
In POP3 mails are downloaded from mail server and stored locally.
IMAP connection should be used within LAN which is an high speed connection.
Following two POP3/IMAP servers can be used by the IITK community.
- qasid.iitk.ac.in:

- newmailhost.cc.iitk.ac.in:
- Can only be used within Intranet via port 143(IMAP) and 993 (IMAPS).
