Training on Spam<\/h2>\n\n\n\n

Train Spam from Junk email directories for email account. Replace USER with the domain admin username, DOMAIN.TLD with domain name, and ACCOUNT with the email address.<\/p>\n\n\n\n

\/usr\/local\/cpanel\/3rdparty\/bin\/sa-learn -p \/home\/USER\/.spamassassin\/user_prefs --spam \/home\/USER\/mail\/DOMAIN.TLD\/.ACCOUNT@DOMAIN.TLD\/.Junk\/{cur,new}<\/pre>\n\n\n\n
Use read emails in inbox as Ham<\/h2>\n\n\n\n
You can use the following script to feed sa-learn ham.  The script looks at all the read messages for the current year in the default inbox and then feeds them individually to sa-learn<\/p>\n\n\n\n
cd \/home\/USER\/mail\/\nfor emailHam in `ls -lt --time-style=long-iso {cur\/,new\/} | grep $(date | awk '{print $6}') | grep \"2,S\" | awk '{print $8}'`\ndo\n\/usr\/local\/cpanel\/3rdparty\/bin\/sa-learn -p \/home\/${cpanelUser}\/.spamassassin\/user_prefs --ham ${mailbox}\/{cur,new}\/${emailHam}\ndone<\/pre>\n\n\n\n
Script to automate the process<\/h2>\n\n\n\n
You can use the following script to automatically train sa-learn.  Create the script and then use Crontab to launch it.<\/p>\n\n\n\n
Script<\/h3>\n\n\n\n
Create a file named sa-learn.sh and add the following contents to it.<\/p>\n\n\n\n
#!\/bin\/bash\n\n# Notes on cpanel mail\n# - \/home\/cpanel_user\/mail <- Default mail directory, all the email accounts are located in the domain.com directory, although there are hidden files in here that point to that.\n# - the default catch all is in ....\/mail\n\ndateYear=`date +%Y`\n\necho \"Starting Training\"\nfor mailbox in `cat mailboxes.txt`; do\n        cd ${mailbox}\n        echo \"training on Ham\" for ${mailbox}\n        cpanelUser=`echo ${mailbox} | cut -d\\\/ -f3`\n        # Check Spam\n        echo \"Trainging on Spam, SPAM, spam, junk, Junk Email, and Junk folders\"\n        \/usr\/local\/cpanel\/3rdparty\/bin\/sa-learn -p \/home\/${cpanelUser}\/.spamassassin\/user_prefs --spam ${mailbox}\/{\".Junk Email\"\/{new\/,cur\/},.Junk\/{new\/,cur\/},.junk\/{new\/,cur\/},.spam\/{new\/,cur\/},.Spam\/{new\/,cur\/},.SPAM\/{new\/,cur\/}}\n        cd\n        # Gets a list of seen messages for the current year to use as Ham\n        for emailHam in `ls -lt --time-style=long-iso {cur\/,new\/} |  grep $(date | awk '{print $6}') | grep \"2,S\" | awk '{print $8}'`\n        do\n            \/usr\/local\/cpanel\/3rdparty\/bin\/sa-learn -p \/home\/${cpanelUser}\/.spamassassin\/user_prefs --ham ${mailbox}\/{cur,new}\/${emailHam}\n        done\ndone\n\n<\/pre><\/div>\n\n\n\n
Create text file to hold mailbox paths<\/h3>\n\n\n\n
You’ll need to create a file called mailboxes.txt and put the email paths for the email accounts you want to run sa-learn against.  The following is an example of what the file should look like.<\/p>\n\n\n\n
\/home\/incredigeek\/mail\/.bob@incredigeek_com\/\n\/home\/incredigeek\/mail\/.larry@incredigeek_com\/\n\/home\/incredigeek\/mail\/.steve@incredigeek_com\/\n\/home\/incredigeek\/mail\/.admin@incredigeek_com\/<\/pre>\n\n\n\n
Create Crontab<\/h3>\n\n\n\n
Add script to cron by running<\/p>\n\n\n\n
crontab -e<\/pre>\n\n\n\n
and paste in the following to launch the script every day at 1AM<\/p>\n\n\n\n
0 1 * * * \/root\/sa-learn.sh train && echo \"training run at $(date)\" >> \/root\/email_report.log<\/pre>\n\n\n\n
Save and you should be ready to go.<\/p>\n","protected":false},"excerpt":{"rendered":"
