 Web mail is an alternative to accessing your email via an email client.  It can be used at any time but is particularly useful when travelling.  Simply point your browser to https://mail.astro.columbia.edu and log in.

+=== Email Quotas ===
 
 There is a 1GB storage limit for every CAL e-mail account.  Your IMAP quota is visible from any IMAP client which supports the QUOTA capability (and most do).  It can also be seen from the [https://mail.astro.columbia.edu/ CAL webmail site].  To view your quota in [http://www.mozilla.com/thunderbird/ Thunderbird] 1.5, for example, select the inbox of your CAL account in the "Folders" pane, and choose `Edit|Folder Properties...` from the menu.  The `Quota` tab in the dialog box that appears shows your quota.

 It is important to keep in mind that you have a limited amount of space on your CAL email account to store email. As mail addressed to your account comes in, it is placed in your Inbox mailbox, and it will stay there indefinitely, until you move it to your personal computer or delete it. When the total amount of email you have in your Inbox exceeds your account's Inbox allotment, new incoming email will be bounced. (Returned to its sender.) Each account has a reasonably large allotment, but if you get a a few -- or even one -- email messages with large attachments, your Inbox can fill up pretty quickly. 
 You will receive a series of automated messages as the size of your Inbox approaches your Inbox quota.

+=== Spam Filtering ===
+
+CAL is running [http://dspam.nuclearelephant.com/ DSPAM] to provide users with personalized spam filters that will adapt to your preferences.  Mail messages determined by a user's filter to be spam will by default be routed into the user's `spam` subfolder (based on the `X-DSPAM-*` headers added by DSPAM).  
+
+If you find a non-spam message in your `spam` folder, you should tell the filter that it made a mistake.  You can do that by simply forwarding the message to `notspam-username@astro.columbia.edu` (replace "`username`" with your CAL username, of course!)
+
+Conversely, if you find a spam message in your inbox, you can retrain your filter by forwarding it to `spam-username@astro.columbia.edu`.  If you conscientiously retrain your filter when it errs, it will be better able to anticipate your preferences in the future.
+
+=== Personalized Filtering ===
+Traditional UNIX-style `.forward` files are not used on the new CAL system.  We're using [http://www.ietf.org/html.charters/sieve-charter.html sieve], an emerging standard for mail filtering.  You can see an example sieve script [source:trunk/packages/cal-meta/src/examples/sieve/cal-default.script here] (this example script is installed by default for all CAL users, and can be found on Configured Workstations at `/usr/share/doc/cal-base/examples/sieve/cal-default.script`. It filters spam into the user's `spam` subfolder based on the `X-DSPAM` headers mentioned above).  If you want to write a new sieve script, simply put it in a text file on a Configured Workstation, and use `sieveshell` to import it to `mail.astro.columbia.edu`.  For example, here is [wiki:dkg] importing a sieve script located at `~/newsieve.script`:
+{{{
+[0 dkg@kalyke ~]$ sieveshell mail
+connecting to mail
+> put newsieve.script 
+> activate newsieve        
+> quit
+[0 dkg@kalyke ~]$ 
+}}}
+You can find some [http://www.cmu.edu/computing/documentation/sieve/sieve.html example sieve scripts] [http://wiki.fastmail.fm/index.php/SieveRecipes online], if you want to experiment more.
