Considered UNSOLICITED BULK EMAIL, apparently from you

<p>3 weeks down the line, many hours phoning Vodacom Customer Care, hours spent in Vodacom Store, for which I had to pay, many reference numbers, but still unable to send emails from my vodamail email address, which I have had for some 20 years. Every time I am told it will be sorted in 2 days, but NOTHING! Where to now Vodacom?? I receive the above message from "Content-filter at smtp3.vodamail.internal ********** WHY ARE MY OUTGOING EMAILS BEING BLOCKED by Vodacom?</p>
