[mlmmj] stripping HTML and attachments

[Florian Effenberger]

Hi,

is there an easy way of stripping HTML and attachments from incoming posts?

Thanks,
Florian

Mlmmj doesn't directly support content filtering such as this, nor does it yet 
have any dedicated way to 'plug in' an external content filter.

However, by piping the mail through a filter before it reaches Mlmmj, this kind of 
thing can be done. Have a look at this:

http://mlmmj.org/archive/mlmmj/2010-01/1635.html

The patch made it into the 1.2.17.1 Mlmmj tarball, so you can easily download it 
if you want to give it a try. It uses altermime to add a footer. I believe 
altermime can also be used to do other MIME-related tasks such as stripping 
html/attachments, so you can probably modify the script slightly to get it to do 
what you want. If you manage it, please write back and let us know how you did it!

(Someone else may yet have a different/better solution, so perhaps it's worth 
waiting a while before trying.)

Smiles,

Ben.

thanks a lot! I hacked it a bit to make it work with stripmime.pl -
here is how it looks like:

=
#!/bin/bash
MLMMJRECIEVE=/usr/bin/mlmmj-recieve
ALTERMIME=/var/spool/mlmmj/stripmime.pl

# check executables
if ! [ -x $MLMMJRECIEVE ]; then
    echo "can't find $MLMMJRECIEVE executable, aborting"
    exit 1
fi

if ! [ -x $ALTERMIME ]; then
    echo "can't find $ALTERMIME executable, aborting"
    exit 1
fi

# read parameters
I=1
PARAM_L=0
while [ $I -le $# ] && [ $PARAM_L = 0 ]; do
    if [ "${!I}" = "-L" ]; then
        PARAM_L=1
    fi
    I=$[$I+1]
done

if [ $PARAM_L = 1 ] && [ $I -le $# ]; then
    MLPATH="${!I}"
else
    echo "parameter -L /path/to/listdir missing, aborting"
    exit 1
fi

if ! [ -d "${MLPATH}" ]; then
    echo "${MLPATH} is not existing or no directory, aborting"
    exit 1
fi

CONTROLD="${MLPATH}/control"

if ! [ -d "${CONTROLD}" ]; then
    echo "${CONTROLD} is not existing or no directory, aborting"
    exit 1
fi

# go to a dir where altermime can write it's tmp-files safely
cd $MLPATH

# pipe the calls
$ALTERMIME | $MLMMJRECIEVE "$@"
=

Basically untested, but seems to work ATM.
