If you want to modify your procmail.rc rules file, then I suggest that you try your rule in isolation first before you break procmail and cause problems.
The first thing to do is to create the file with your test rule in it.

  • pico proctest.rc
    PLAIN TEXT
    C:
    1. SHELL=/bin/sh
    2. TESTDIR=/home/rollingr/test
    3. MAILDIR=${TESTDIR}
    4. LOGFILE=${TESTDIR}/results.log
    5. LOG="--- Logging for ${LOGNAME}, "
    6.  
    7. #Troubleshooting:
    8. VERBOSE=yes
    9. LOGABSTRACT=all
    10.  
    11.  
    12. ##Insert your rule here instead of sample ##
    13. # Start of sample recipe to bounce blacklisted mail
    14. :0
    15. # Test whether required user is in any of these fields
    16. #Original-, Resent-, To, Cc, Bcc,.X-Envelope-To, Apparently-To or -Resent-To
    17. * ^TO_requireduser@mydomain.com
    18. # If match found then
    19. {
    20.   # Check if the sender is whitelisted
    21.   # Lock destination file for writing if match
    22.   :0:
    23.   # Extract headers From, Sender, Reply-To, Return-Path, To
    24.   # and compare to entries in white.list
    25.   # Entries should take form [email]me@my\.domain[/email]
    26.   # otherwise dot will match any character
    27.   # grep case insensitive, supress errors
    28.   # Click for a full explanation of [url=http://unixhelp.ed.ac.uk/CGI/man-cgi?egrep]egrep[/url]
    29.   * ? formail -x"From" -x"From:" -x"Sender:" \
    30.       -x"Reply-To:" -x"Return-Path:" -x"To:" \
    31.       | egrep -is -f white.lst
    32.   # If match found, deliver to /path/to/mailbox and stop
    33.   /path/to/mailbox
    34.  
    35.   # Bounce unwanted mail
    36.   # Start test - strip body from message
    37.      :0 h
    38.     # If not from mailing daemon
    39.     * ! ^FROM_DAEMON
    40.     # and not bounce of a bounce
    41.     * ! ^X-Loop: bounced@mydomain.com
    42.     # then pipe header with extra bounced header and error message in body to sendmail and stop
    43.     | ( formail -rt -A "X-Loop: bounced@mydomain.com"; \
    44.         echo "Your email address is not on our whitelist.  Please go to [url]http://www.mydomain.com/whitelist[/url] and subscribe"; \
    45.         ) | $SENDMAIL -t
    46.  
    47.   # If we got this far, then message is on blacklist and was previously bounced or is from the mailing daemon, so throw it away and stop
    48.   # Bin everything else sent to this user (such as bounces)
    49.   :0
    50.   /dev/null
    51. }
    52. # if not to required user then continue processing
    53.  
    54. ## End of sample Recipe ##
    55.  
    56.  
    57. # Catch anything that failed test Recipe here
    58. :0
    59. ${TESTDIR}failed.mail

    Now we need to create the supporting files

  • pico white.lst
    anyuser\@gmail\.com
  • Generate a valid message file which will trigger the rule
    PLAIN TEXT
    CODE:
    1. From anyuser@gmail.com  Wed Nov 15 08:48:26 2006
    2. Return-Path: <anyuser@gmail.com>
    3. Received: from ug-out-1314.google.com (ug-out-1314.google.com [66.249.92.170])
    4.         by mydomain.com (8.11.6/8.11.6) with ESMTP id kAFFmPd29195
    5.         for <me@mydomain.com>; Wed, 15 Nov 2006 08:48:25 -0700
    6. Received: by 10.66.252.9 with HTTP; Wed, 15 Nov 2006 07:48:23 -0800 (PST)
    7. Message-ID: <6757a1050611150748h6b0ada1fkf4dfe9aaefe721db@mail.gmail.com>
    8. Date: Wed, 15 Nov 2006 15:48:23 +0000
    9. From: "Sender" <anyuser@gmail.com>
    10. To: "Recipient" <me@mydomain.com>
    11. Subject: Testing Mail Header
    12. MIME-Version: 1.0
    13. Content-Type: text/plain; charset=ISO-8859-1; format=flowed
    14. Content-Transfer-Encoding: 7bit
    15. Content-Disposition: inline
    16.  
    17. This is a test for procmail
    18.  
    19. --

    Next create a batch file to run the rule. Point TESTDIR to your directory.

  • pico procmail.bat
    PLAIN TEXT
    C:
    1. #!/bin/sh
    2. #The executable file named "proctest"
    3. #
    4. # You need a test directory.
    5. TESTDIR=/home/yourlogin/test
    6. if [ ! -d ${TESTDIR} ] ; then
    7.   echo "Directory ${TESTDIR} does not exist; First create it"
    8.   exit 0
    9. fi
    10. #
    11. #Feed an email message to procmail. Apply proctest.rc recipes file.
    12. #First prepare a mail.msg email file which you wish to use for the
    13. #testing.
    14. procmail ${TESTDIR}/recipe.rc <mail.msg
    15. #
    16. #Show the results.
    17. less ${TESTDIR}/results.log
    18. #
    19. #Clean up.
    20. rm -i ${TESTDIR}/results.log
    21. rm -i ${TESTDIR}/failed.mail

  • And make it an executable
    chmod u+x procmail.bat
  • Run the test
    procmail.bat
