 Print Queue   | Description
---------------------------------------------------------------
 lp1           | Large HP 4100 B&W printer in RI 274
 lp1m          | Large HP 4100 B&W printer in RI 274 (Manual Feed)
 lp1s          | Large HP 4100 B&W printer in RI 274 (Single Sided)
 lpc           | Xerox Color Phaser 6300DN in RI274
 lpcm          | Xerox Color Phaser 6300DN in RI274 (Manual Feed)
 lpcs          | Xerox Color Phaser 6300DN in RI274 (Single Sided)
 ps284         | Xerox Color Phaser 6300DN RI 284
 ps284m        | Xerox Color Phaser 6300DN RI 284 (Manual Feed)
 ps284s        | Xerox Color Phaser 6300DN RI 284 (Single Sided)

First, open the printer setup utility (System Preferences -> Print & Fax -> Set Up Printers). If the printer queue that you want appears automatically under "Shared Printers", you're already done: just click the checkbox on the left so that it will be listed as an option in your applications.

Otherwise, click on Add, and when the new printer dialog window comes up, choose:

IP Printing
Printer Type: Internet Printing Protocol
Printer Address: theory.uchicago.edu
Queue Name: [choose your queue: "lp1" and "color" are useful options]
Printer Model: [might not be necessary, but shouldn't hurt]

Unfortunately, a second step using the terminal command line is necessary. Open a terminal window, and type "lpstat -v". This will show a list of all available print queues and the address associated to each one. You should recognize the queue that you just added; it may look something like:

device for lp1_on_theory.uchicago.edu: ipp://theory.uchicago.edu:631/ipp/lp1

The correct address is slightly different, so we use the "lpadmin" command to change it. Making sure to substitute the appropriate print queue name(s) in two places, type:

lpadmin -p lp1_on_theory.uchicago.edu -v ipp://theory.uchicago.edu:631/printers/lp1

As you can see, the only change is replacing the directory "ipp" with "printers". After this change, the printer should work perfectly well.

For reference, this hint came from the following website: http://www.macosxhints.com/article.php?story=20031210081441221

On the control panel of the printer, use the four arrow keys surrounding the green button with the OK/check mark to maneuver within the menus. Use the OK/check button to select an item.

1. Scroll down and select "Send options"
2. Select "email"
3. You will see a standard email address header in the display; fill in the From, To, Cc, and Subject fields as needed.
4. Place your document on the scanner glass for a single page, or in the document feeder if you have multiple pages. Press the "Start" button to scan and send. The document will appear in the inbox of the designated recipient as an email attachment, one attachment for each page. The machine keeps the settings for up to a minute if you have additional scans that you want sent to the same email address -- just place the next document in the feeder or on the scanner glass and press "Start" again.

The HP 4101mfp can be configured to scan documents into several formats: pdf, tiff, m-tiff, and jpeg. To configure the machine, press the "Menu" button. Scroll down and select in order
a. "Configure device"
b. "Sending"
c. "Email"
You will then see options to select B&W/color scans, as well as the file type (pdf, tiff, m-tiff, jpeg). Do not attempt to modify the other settings!

How do I arrange to have junk mail either deleted from the mail spool file (ie the incoming queue), or shunted off to a junk mail file?
How Does Authenticated SMTP work?
How can I use the Beta version Blacklist?
How can I make spamassassin learn what I think is spam?
I want to make a whitelist, how do I do that?

The easiest way to do this is through the use of procmail filters.  
Procmail filters will accept regular expression.  Here is a quick 
recipe for moving mail labeled as "SPAM" to a junk spool.

:0:
* ^X-Spam-Status: Yes.*
$HOME/mail/Junk

Just write that to a file in your home directory called .procmailrc 
and everything  that is labeled with the "X-Spam-Status: Yes" line 
by spam assassin will be moved to the mail/junk file in your home 
directory.

For more information about procmail filters and recipes go to 
http://www.procmail.org/

For additional information and recipes for configuring
your .procmailrc file for filtering, consult the man pages,

man procmailex

or visit the procmail mailing list archive

http://www.xray.mpe.mpg.de/mailing-lists/procmail/

where you can search for answers to your problem,
and perhaps not reinvent the wheel.

The theory server now has a beta version email blacklisting program.  It takes several IP addresses from a few reliable external blacklisting organizations (more may be added later).  All you have to do is put these lines in your .procmailrc:

:0 wh
* ? /bin/checkblack
/home/<userid>/mail/Junk

This will use filters from abuseat.org.  We also get 3 lists from uceprotect.net which you can also use.  You must also have the above lines in your .procmailrc, but now you must also create a .blist file in your home directory.  Mine looks like this:

level1=yes
level2=no
level3=no

I recommend this configuration.  You can say yes on any none or all of the lines  but be advised that level1 will give you no false positives, level2 may give you some and level3 will likely give you some.

This tool will also give you access to the use of a .blacklist file in your home directory.  If you use a .blacklist be sure to use CIDR notation.  You can use straight IP addresses (192.168.10.1) or network addresses (192.168.10.1/24).  For a full explanation of CIDR go here http://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing

This is really quite simple.  Spamassassin has a bayes filter in it by default.  All you need to do is tell it what you think is "spam" and what you think is "ham" (yes that is what they call good emails).  Start by creating a Junk or Spam folder  and then create a Ham folder.  Now all you need to do from the command line is enter this command:

theory$ sa-learn --showdots --mbox --spam spam-file
theory$ sa-learn --showdots --mbox --ham ham-file

This should help curb may unwanted emails.  For more details look here:
http://wiki.apache.org/spamassassin/BayesInSpamAssassin

This is easy to do with procmail.  All you need to do is put the following lines in your .procmailrc:

:0E
* ? (echo "$FROM" | $FGREP -i -f /home/<userid>/.white)
/var/mail/<userid>

Now create a .white file in your home directory.  In this file enter the users you want to always receive email from one address per line like so (Regular Expression   and partial addresses are both acceptable):

manager@theory.uchicago.edu
bob@goodemailers.com
williamshakespear
google.com
@gmail.

You may also use this for blacklisting by substituting /var/mail/<userid> with /home/<userid>/mail/Junk and perhaps renaming .white to .black.
