How to setup TMDA for SuSE Linux

This page explains howto setup the Tagged Message Delivery Agent, a very fine program to filter spam, on your SuSE Linux machine.

1. Installation:

• Download the latest tmda source tarball
• Untar it: tar -xzvf tmda-1.0.3.tgz
• Edit the tmda.spec file
  vi tmda-1.0.3/contrib/tmda.spec
  and replace the 2 occurences of /usr/bin/python2 with /usr/bin/python
  BuildRequires: /usr/bin/python
Requires: /usr/bin/python
• Precompile the python files
  cd tmda-1.0.3; ./compileall ; cd ..
  
• Tar it again: tar -czvf tmda-1.0.3.tgz tmda-1.0.3/.
• Generate the rpm (as root): rpmbuild -tb tmda-1.0.3.tgz
• Install the rpm (as root): rpm -Uvh /usr/src/packages/RPMS/noarch/tmda-1.0.3-1.noarch.rpm

2. Configuration

You may want to generate a ~/.procmailrc-tmda file to process mail after TMDA's filtering.
If you already use procmail, rename your ~/.procmailrc to the above.

Add the following to a new ~/.procmailrc file

##Preliminaries
SHELL=/bin/sh			#Use the Bourne shell (check your path!)
MAILDIR=${HOME}/Mail            #First check what your mail directory is!
HOSTDOMAIN=`/bin/hostname -d`

# set the environment variables
EXTENSION="$1"
:0
* EXTENSION ?? .
{
  DELIMITER="+"
}
RECIPIENT="$LOGNAME$DELIMITER$EXTENSION@$HOSTDOMAIN"
SENDER=`formail -x Return-Path | sed 's/[<>]//g;s/^[ ]*//'`

# Finally, run the message through tmda-filter.
:0 w
| /usr/bin/tmda-filter

# Take the exit code from TMDA.
EXITCODE=$?

# TMDA takes care of final delivery
DEFAULT=/dev/null

Set the following variables in your ~/.tmdarc or /etc/tmdarc

MAIL_TRANSFER_AGENT = "sendmail"
DELIVERY = "|/usr/bin/procmail -f $SENDER ~/.procmailrc-tmda"
RECIPIENT_DELIMITER = "+"

Now proceed with the TMDA client configuration as explained on the web site.
