There seems to be an increase in Spam (no surprise there) but I also notice that we have to train messages daily, whereas it used to be a few a week. Is this because the spammers are gaining, and coming up with new ways to get in? Is this all a lost cause?
Please see this page.
Probably not—I haven’t seen new types of spam in a while, and reports of spams getting through are low this month.
No.
