CSID, @CS Email, Xenon

CS and CSE students receive a CSID which entitles them to an @cs email address and an account on xenon. These are good for life, assuming the student graduates from the CS department. Current students can also use their CSID's to access the PUP cluster in the basement of Gates (B21).


How do I forward my @cs email?

When first declaring, the course advisor should help you set your @cs email address to forward to an email address you check regularly. (Many students use their Stanford email address.) You can change this at any time in Pedit or by running "pedit" on xenon.

How else can I access my email?

If you want to check your email on Xenon, forward your mail to csid@xenon.stanford.edu. If you forward your mail to Xenon, it can be used as an IMAP or POP3 mail server. You can also use pine or elm. Xenon also runs a webmail client. If you want a more complicated forwarding system, you can use Xenon to forward your mail again. Log into xenon and run "/usr/local/bin/help forward" at the command prompt. This will give you a detailed description of how forwarding can be set up on Xenon.


How do I access Xenon?

Xenon is accessible through SSH. Your CSID is your username. You can log in from any unix machine on campus by running "ssh csid@xenon.stanford.edu". For security reasons, it is not possible to telnet into Xenon. You must use SSH or another secure protocol. For more information about secure login, including alternative login methods, see the CSD security page.

What can I do on Xenon?

Xenon should not be used to run coursework; it is for email and text based applications only. The two main programs that you might find useful are pedit (personal edit) and medit (mailing list edit). You can run both "pedit" and "medit" from the command line. Pedit is used to edit your personal and contact information such as email forwarding address, aliases, office location, mailing address, and telephone number. Pedit is also useful for looking up the contact information of other people's profile information. Medit is used to create and manage CS mailing lists. Both Pedit and Medit have web interfaces, accessible from the CS homepage under the "Tools" menu.

How much space do I get on Xenon?

Current CS students get a 30 MB quota and 4 MB for their mail spool directory. Alumni get a 10 MB quota and 3 MB for the mail spool directory. Quotas may also be in place on temporary directories such as /var/tmp. Use the command 'quota -v' to view quotas and usage.

I forgot my Xenon password!

If you have a problem with your password, email action@cs and visit Gates rooms 161-170 during business hours. Bring your Stanford photo ID with you.

I declared CS but still can't log into Xenon!

Declarations may take up to two weeks to process and students do not receive Xenon until declarations have been officially completed. If it has been longer than two weeks since you declared and you are still unable to log in, email the course advisor.

More Information


With CCRMA Webmail you can access your email from a web browser by visiting:


Type you username and password in the login field and you are in. If it's your first time using the program, it will ask you to specify some settings then bring you to your Inbox. Webmail defaults to the '' directory (in your home directory '') for storing your various email folders. This folder is convenient for use with IMAP clients as well. Webmail also allows manipulations of files and directories in your home directory through 'WebDisk.' Check that out.

SMTP Outgoing

SMTP Server:


IMAP Receiving

CCRMA Secure IMAP server:


This server requires 'SSL' (the secure connection), and authentication: your CCRMA username and password.

As part of its configuration, your IMAP client should also have a place to enter your IMAP folder. This is an important part of using IMAP, since this folder will contain all your email folders and subfolders in one location, so that any IMAP client accessing email will show the same set of folders no matter which client you use (the advantage of IMAP). Make sure you have a folder called at the top level in your home directory. So, when configuring IMAP, enter as the IMAP folder (or sometimes called the folder 'Namespace'). This way, your email client will know were to look for it's folders, rather than having to search throughout your home directory, which adds significant time to starting your email client.

Unfortunately, IMAP filters are not yet supported with the CCRMA system. This means that you will have to see any filters manually on each client.

Configuring your personal Email Clients with IMAP and SMTP

CCRMA recommends secure IMAP (rather than POP) for your personal Email clients (Apple Mail, Outlook, and any Linux clients). Secure POP is, however, available.

SMTP Outgoing

From inside Stanford

To send email from inside the Stanford network (campus wide), you can point any email client to:


Authenticatioin is not required.

From outside Stanford

For users with a SUID, Stanford offers a 'roaming' smtp server, which requires authentication with your SUID username and password:


As part of this configuration, don't forget to enable: "This server requires authentication" (or some such statement) and enter your SUID and password. In the end, you can configure your email client to send using this server, whether or not you are inside the Stanford network. So, if you plan to take your machine off campus at all, you may want to just use this option.

If you don't have a SUID, you will have to use for outgoing email while on campus, but use your own ISP SMTP server (e.g. ) for outgoing mail while at home, off campus. If you are not at home, or don't know the SMTP server for your location, you'll have to use CCRMA Webmail or pine to send CCRMA email. Or use X11 display forwarding, and use one of the Linux clients display forwarded to your machine, which is essentially like sending email locally from a CCRMA workstation (and thus from within the Stanford network).

IMAP Receiving

Use the same process outlined above: IMAP Receiving.


Pine is a terminal based email program. That means that you use it from inside a terminal window by typing:

~> pine

This program is especially good when you have low bandwidth access. Some CCRMA users prefer this program to any others. Conveniently, it uses the same IMAP folder as Webmail ('': see IMAP below) so that you can configure all your mail clients to source the same set of folders (the joy, as it were, of IMAP).

Here's what it looks like:

It is a very simple program based on the 'pico' text editor. It does take some getting used to however. Its advantage is that it requires less internet bandwidth to work, so it's great for quick reads and access in remote locations. Lots of CCRMA folks love this program, so don't hesitate to ask around. There is no mouse interaction, but lots of arrow and single text key input for navigation and email functions.

Email Forwarding

Since we are using SpamAssassin for spam control at CCRMA using the system of forwarding is no longer supported. Please, do not use a file at CCRMA. Forwarding is therefor better done in . See [1] for how to do this.
