Using Webmail

Webmail provides a secure means for accessing your CS e-mail from outside (or inside) the department using a web broswer.


Webmail is not as feature-rich as some mail clients, but it can provide a useful and secure connection to your e-mail when all you have available to you is a graphical web browser, such as Firefox or Internet Explorer, which supports an encrypted (ie, secure) connection.

Webmail supports the following features:

The only storable preferences currently supported are: full name, e-mail address, language, and signature.

Sent mail (messages that you send) is saved in a mailbox named sent-mail in the selected mail folder collection (a directory, usually mail/ If you have selected a different folder collection, the sent-mail mailbox will be created or appended in that directory. Currently, Webmail does not provide a preference selection for the name or location of the sent-mail mailbox. If you prefer to use a different name such as outbox you can make sent-mail be a symbolic link to outbox, and sent messages will be appended to that mailbox. For example:

	% cd ~/mail
	% ln -s outbox sent-mail 


To run Webmail, you will need:


To use Webmail, go to and login with your CS UNIX username and password (not your Duke NetID).

If the CS Webmail server is not accessible, you can also use the Duke webmail server,, and select Computer Science Mail in the pull-down menu. This provides a secure connection to the CS IMAP mail server, with an identical interface. You will also here need to login with your CS UNIX username and password in order to access the CS IMAP server.

Please refer to the Roundcube Roundcube User's FAQ page for additional information.



Our Webmail installation is configured to only allow connection to the CS IMAP e-mail server.

Webmail is written in PHP, and uses a MySQL database back end.
