Get a lot of spam — use spamassasin.

If you get a lot of spam into your local inbox and do not want your service provider to filter them for you, like me :), then you can use spamassasin.

The benefit with this approach is that all the spam will be delivered to your local inbox and you do not need to do anything on the server. You can blacklist, whitelist, report message as spam all on your client and it would not change anything on the server. So you control your mail, isn&#8217;t that great.

#The config and the output file

open (CF_FILE, &#8221;<Config.test&#8221;);
open (OUT_FILE, &#8221;>test.csv&#8221;);

# No need to change anything below this.
