We are receiving in our server tons of Spam emails with Subjects like this:
M___crie as suas proprias estampas 391
As you can see, it has at least two underscore characters ( __ ) and I think this would be the only way to scan them.
So, please, could anyone help me giving me the correct configuration of a rule to flag as SPAM this kind of emails?
I was told not to configure local rules at those several .cf files in /etc/mail/spamassassin, because of update tasks, but to do this at my local.cf. So, please, see my current local.cf file below. Thanks for any help.
Mario./
