---------------------------------------------
A rarely used legacy misfeature of the main Internet email protocol
creeps back from irrelevance as a minor annoyance. You should ask your
mail and antispam provider about their approach to SMTP callbacks. Be
wary of any assertion that is not backed by evidence.Even if you are an
IT professional and run an email system, you could be forgiven for not
being immediately aware that there is such a thing as SMTP callbacks,
also referred to as callback verification. As you will see from the

∗∗∗ Reverse Javascript Injection Redirects to Support Scam on WordPress ∗∗∗
---------------------------------------------
Over the last few weeks, we’ve noticed a JavaScript injection in a
number of WordPress databases, and we recently wrote about them in a
