Spamandclam.sh

From Kolab wiki

spamandclam.sh

This bash script will update your spam dbs from a central shared folder. It needs amail.pl to send confirmation email. The script also updates to the latest clamav antivirus patterns though this is not really required. The Kolab Server updates every hour anyway.

spam.sh

Second example (tested on Kolab 2.2.1 RC1), you can run it as kolab-r from cron.

This example deletes after learning the items in shared spam and ham folder.

It start sa-learn only if it find emails to learn in one of the both shared folders,

so you can run it every 15 minutes from cron.

We don't need to start freshclam anymore from this script.

Put it in to /kolab/data directory together with amail.pl. Then chown kolab-r:kolab-r -R /kolab/data
