Dropping More Spam at ISP

From: "andrew cooke" <andrew@...>

Date: Sat, 21 Apr 2007 12:18:21 -0400 (CLT)

I receive a fairly large amount of spam - around a thousand emails per
day.  That wouldn't be a problem, since filters reduce it to almost
nothing, except that if my local server goes down I end up with a rapidly
growing backlog on acooke.org.

A long time ago the guy that runs acooke.org sugegsted I filter email
based on user name, since a large fraction of the spam was addressed to
someone other than me (eg i-am-a-spammer@...).  Today I finally
implemented that.

Here's the config:

[acooke@... acooke]$ cat .procmailrc

# finally implementing something suggested a long time ago...


# default (if not spam) falls through to system spool for pop retrieval
# spam copied to mboxes
# mboxes are cleaned out by cron once per day

# if there's an acooke.org address, but it's not a recognised user,
# then it's spam.

* ^(To|Cc|Bcc)[ :].*@acooke.org
* !^(To|Cc|Bcc)[ :].*razor\-songbird@
* !^(To|Cc|Bcc)[ :].*(pauli|paulina|plt)@
* !^(To|Cc|Bcc)[ :].*(andrew|acooke)@
* !^(To|Cc|Bcc)[ :].*(jara)@
* !^(To|Cc|Bcc)[ :].*(root|postmaster|webmaster)@
  # if razor indicates spam, discard in mbox-razor
  # (i used to do this to everything, but this way allows me to
  # whitelist on my local machine)
  :0 Wc
  | /www/u/acooke/bin/razor-check
  :0 Wa

  # otherwise, report and save
  :0 c
  | /www/u/acooke/bin/razor-report

Note - the only issue I had installing razor, after following there
instructions, was an error indicting that some files were not found in
@INC.  It turns out that, if you install in a non-standard directory like
~ you need to add not just ~/lib, but also ~/lib/perl5/site_perl to


But allow c[omp]ute through!

Just checking - the original filter (above) blocked posts here.
