===== SCS Email =====


The School of Computer Science offers Email accounts for students, faculty and staff. The SCS email service offers:

  * web-mail access from anywhere on the internet
  * imap access
  * 1 GB inbox quota
  * spam protection
  * SSl/TLS connections to our mail server - this allows to configure your home system to be able to route all outgoing e-mail through SCS servers



==== Web-mail ====

<note warning>The School is currently transitioning to a new mail server, the documentation below refers to the new **mail** server. If you have not created a new account or have not been moved to the new server then you cannot use the links below!</note>

You can access your SCS email through one of two web-mail clients.

  * Largest incoming mail size: 75Mb

==== Spam Protection ====

SCS uses the following spam protection:

  * Greylisting ((Greylisting is set to a 1 minute delay))
  * Spam Assassin

=== Spam Assassin ===

You can enable personal spamassassin settings by adding the following to your homedirectories .procmailrc file:

<code>
SHELL=/bin/sh

# Enable personal spamassassin settings:0fw: spamassassin.lock
* < 256000
| spamassassin
</code>

Once you receive your first message a default .spamassassin directory will be generated. There you will find a user_prefs file which you can edit. The file also allows for personal blacklists and whitelists and you can alter the spamassassin-score. 

What does Spam Assassin do?

Spamassassin will tag an email as spam in the email header and on the Subject line. The Subject line will have [SPAM ++++++] where the + signs indicate the spam level. Now its up to the user (you) what you want to do with those emails. There are email clients that can identify emails labeled as spam and can remove them.((Thunderbird has spam filtering options))

=== Deleting blacklisted emails ===

You can add a procmail rule that will delete all your personal blacklisted emails. here are the steps to enable it:

  - Add a .procmailrc file on [[http://www.scs.carleton.ca/nethelp/doku.php?id=services:external_access_host_access | access]]/lambda (see code below)
  - Once you receive an email with the procmail code enabled it will generate a file called .spamassassin/user_prefs. Edit this file and add your blacklisted email of the form "blacklist_from somewhere@somesite.com"
  - Check the logfile .spamassassin/procmail.log if your procmail script deleted any messages

Here is the ~/.procmailrc file that can delete blacklisted emails using a combination of spamassassin and procmail filtering:

<code>
SHELL=/bin/sh
TRASH=/dev/null
LOGFILE=$HOME/.spamassassin/procmail.log
VERBOSE=no

# Enable personal spamassassin settings
:0fw: spamassassin.lock
* < 256000
| spamassassin

# Remove all spamassassin spam scored 50 (blacklisted emails)
:0
* ^Subject:.\[SPAM \+\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+\
+\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+\]
$TRASH
</code>

You can add this file in your SCS account accessible through [[ http://www.scs.carleton.ca/nethelp/doku.php?id=services:external_access_host_access|access]] or the [[ http://www.scs.carleton.ca/nethelp/doku.php?id=accounts_and_labs:the_linux_network|lambda linux network]].

==== Forwarding Mail ====

You can forward mail by logging into access.scs.carleton.ca and creating .forward file. 

The .forward file can have a single forward:

<code>John Doe <jdoe@hotmail.com></code>

or you can deliver a copy in your inbox plus forward a copy:

<code>
/jdoe
John Doe <jdoe@hotmail.com>
</code>

You can also create a list of forwards (one entry per line):

<code>
John Doe <jdoe@hotmail.com>
Jane Smith <jsmith@gmail.com>
Homer Simpson <hsimpson@yahoo.com>
</code>

Make sure your .forward file has perms '-rw-r--r--':

<code>chmod 644 ~/.forward</code>

==== Mail Folders ====

There are two different mail formats:

  * mbox - single file that holds many emails
  * maildir - directory of separate mail files

The SCS server stores files in maildir format on the server INBOX and can read mbox files on your local account.
