How to install dspam in 5.0

[dfriestedt]

Here is how I did it, for those of you wondering how to get dspam to work w/ 5.0

nano /opt/zimbra/conf/amavisd.conf.in

uncomment this line
#$dspam = '/opt/zimbra/dspam/bin/dspam';

Save

chown -R zimbra:zimbra /opt/zimbra/dspam-3.8.0


nano /opt/zimbra/bin/zmtrainsa

replace
for f in ${spamdir}/*; do
test -f ${f} && ${zimbra_home}/dspam/bin/dspam_corpus --addspam zimbra ${f}
done
for f in ${hamdir}/*; do
test -f ${f} && ${zimbra_home}/dspam/bin/dspam_corpus zimbra ${f}
done

with
${zimbra_home}/dspam/bin/dspam_train zimbra ${spamdir} ${hamdir}


That should do it....

Great summary!

Additionally you should uncomment the Dspam cleanup lines in crontab.

crontab -e

..... and you also need the 'Feature Chained' changed to 'Tokenizer chain' in the dspam.conf.

I looked at /opt/zimbra/bin/zmtrainsa and saw this lines:

  if [ x"$DSPAM" = "xenabled" ]; then
    timestampit "Starting dspam training"
        ${zimbra_home}/dspam/bin/dspam_train zimbra ${spamdir} ${hamdir}

    ${zimbra_home}/dspam/bin/dspam_clean -p0 $USER
    timestampit "Finished dspam training"
  fi

  if [ x"$DSPAM" = "xenabled" ]; then
    timestampit  "Starting dspam $MODE training for $USER using folder $FOLDER"
    if [ $MODE == "ham" ]; then
            MODE="innocent"
    fi

    ${zimbra_home}/dspam/bin/dspam --user zimbra --class=${MODE} --source=corpus --mode=teft \
      --feature=chained,noise --stdout

    ${zimbra_home}/dspam/bin/dspam_clean -p0 $USER
    timestampit  "Finished dspam $MODE training for $USER using folder $FOLDER"
  fi

Should $DSPAM be set to "enabled"? If yes where should I do it? In this file?

Also found this in bugzilla

This problem still occurs in ZCA 5.x, relevant code from the zmfixperms script
is here:

if [ -L ${zimbra_home}/dspam ]; then
printMsg "Fixing ownership and permisions on ${zimbra_home}/dspam"
chown ${root_user}:${root_group} ${zimbra_home}/dspam-*
chown -R ${root_user}:${root_group} ${zimbra_home}/dspam/*
fi

ownership should be zimbra:zimbra for these directories/files.

This can be an annoying problem if you're doing a disaster recovery and apply
this script expecting that DSPAM to be working (obviously after enabling it in
current versions), unless you check the logs it can be easy to miss.

The corrected code for zmfizperms should be:

if [ -L ${zimbra_home}/dspam ]; then
printMsg "Fixing ownership and permisions on ${zimbra_home}/dspam"
chown ${zimbra_user}:${zimbra_group} ${zimbra_home}/dspam-*
chown -R ${zimbra_user}:${zimbra_group} ${zimbra_home}/dspam/*
fi

Shouldn't the last two lines in the crontab entry for log cleanup be the following instead?

/opt/zimbra/dspam/bin/dspam_logrotate -a 60 -l /opt/zimbra/dspam/var/dspam/system.log
/opt/zimbra/dspam/bin/dspam_logrotate -a 60 -d /opt/zimbra/dspam/var/dspam
