Passing Text from MySQL into spamassassins Spamc Client

Question

This is my first post here and I am a bit of a nub. I am looking to pass text from a MySQL database through spamassains spamc client. I can do it by writing to a file and then passing this file into spamc as in spamc < 'textfile.txt' but this is slow, due to the disk read/writes.

Does anyone know how to do this directly?

Answer 1

Echo the query into the command line client in batch mode via a pipe, then pipe the output to spamc:

echo "SELECT col1, col2 FROM yourtable" | mysql --batch -uuser -ppassword | spamc

I am assuming you are selecting complete email messages from your database. If not, you will receive several spam flags for missing headers. Here's an example I just ran...
