INTRODUCTION

   o   Are you sick of getting spam emails ?
   o   Doesn't an email to postmaster/abuse stop it ?
   o   You can't preview emails before download to kill unwanted mail ?
   o   You don't want to be online to kill unwanted emails - correct ?

If you can answer yes to all of these questions, then this will might be
the solution for you.

If your ISP mailserver uses Procmail to deliver emails to you, and the
account you have is at the same server as the email server, you can use a
file in your $HOME dir called '.procmailrc'. This is a filter file that can
sort, forward, copy, a.s.o., all e-mails you get. You don't even have to be
online to activate it - it's all done automatically locally at your ISP's
machine at every new e-mail that arrives for you. You can also use Procmail
to remove unwanted emails and that is what this package is based on.

This script will automagically create a .procmailrc header file if you don't
already have one. When you get an e-mail or news message that you don't want
to receive in e-mail in the future you just invoke the script. It will then
format and add the domain of the current message header as an entry in the
.procmailrc file on your disk. The entry tell Procmail to send these
messages to /dev/null (ala NIL:) next time you get email from this domain in
your $HOME dir at your ISP. it will be handled while you're not there as
well. Next you can optionally upload the updated .procmailrc file to your
account.

I have experienced that this has reduced spam mail to about zip-zero at my
account. I may get a spam mail once a week or less from a new domain, but it
gets added to the .procmailrc file immediatly and then emails from this
domain cannot be downloaded by Thor (or YAM, Elm, Pine for that matter if
you use those instead..) in future. Also a big thanks to Petter Nilsen/
Ultima Thule for providing me with more than 700+ domains used in the
.procmailrc file in the archive.


USAGE:
------

1) Install the script 'AddProcmail.thor' in Thor:Rexx/
2) Edit the header in the arexx script (see right below here)
3) Assign the script to a function key in Thor for convinient use

EmailFlag=0

You may have to change the following lines in the .procmailrc header:

---
PATH=/bin:/usr/bin:/opt/bin
MAILDIR=$HOME/Mail
LOGFILE=$HOME/log.procmail
---

From: FAQ Editor <faq-editor at ii.com>

1]  To find out if procmail is on your system and what the full path to
    it is, type one of the following commands:

      Shell      Command
      =====      =======
      csh        which procmail
      sh or ksh  type procmail
      various    whereis procmail
      various    where procmail

Ask your netadmin for details!

That's it.

You may change the behaviour of Procmail. I think redirecting unwanted
email to /dev/null is the best solution (default behaviour) to avoid
mail-loops, wasting bandwith and such. You can automate it to send a copy
of the message to an abuse at  or something as well (read the man files of
Procmail for more information on this - see links below).

NOTE that the search routine assume that there is four lines for each entry.
If you change the number of lines each entry creates you must also modify
the search routine. Please do not add comments between the entries after the
first one.

USAGE WITH NCOMM:
-----------------

I have provided an example NComm script that can be used in conjunction with
the arexx script. You must probably modify it quite much to suit your ISP
login proceedure. It is just meant as an example on how you can automate the
login procedure. Personally I am always watching the proceedure so I haven't
added support for NO CARRIER and so on in the Ncomm script.

Add a new phonebook entry in NComm and call it "MyBBS" (where MyBBS is
anything you want to call it..). Set path and name on script in the Script:
entry of the phonebook. Set your ISP password in the Password: entry of the
phonebook and finally save.

Modify the arexx script (Addprocmail.thor) where BBSentry = "MyBBS" and
set Upload = 1. Next time you add a new entry you will be asked if you want
to upload the new modified script. If you select "Upload" the arexx script
will invoke Ncomm (start it if it isn't already started) and dial the
"MyBBS" which again starts the Ncomm script (too complicated hu?).

Note that you can easily make this arexx script work with f.ex. Term by
writting a simple arexx script. If you do I would like to distribute it with
future versions of AddProcmail. Please send contribution (which will be
credited) to the e-mail address above.


EXTRAS
------

I have provided a .procmailrc file with several hundreds (700+) domains that
will be stopped before you get them in your e-mail. Almost every entries are
collected by Petter Nilsen (thanks Petter!). Converted to .procmailrc file
by myself.


NOTES:
------

- You will need telnet or shell login access to your ISP to use Procmail.
  AddProcmail is of no use if your ISP doesn't use Procmail.
- You will also need your account to be on the same place where the mailserver
  is (AFAIU).
- I am not a Unix expert nor a Procmail expert. Please refer to the man
  files of Procmail(rc) and/or your Internet provider with questions about
  how and if you can get Procmail to work with your system. Simply ask your
  ISP adm. if you can use .procmailrc files with your email address to
  filter emails. They should be able to inform you if you can or not.
- Check resource references above for more information on Procmail.
