I've called the big guys to help you. Good luck.

Thank you

I get a lot of messages, over time, that say that they are from me. Inspection of the message source almost always reveals that someone else sent them.

First check: do any of these appear in your "Sent" folder?

Second check: if you get one of these messages, use ctrl+u to see its "source". There will be a lot of technical jargon stuff, but look for the "From:". It will often have your name but someone else's email address. This item is fairly easy to falsify, so a spammer can insert stolen addresses. He won't put his own there.

Thanks , this is portion of what it says, I have removed most of my email address Return-path: <info@.............................co.uk> Envelope-to: info@................................co.uk Delivery-date: Tue, 05 Apr 2016 14:24:54 -0400 Received: from [116.98.30.27] (port=24611) by jupiter.dnsprotect.com with esmtp (Exim 4.86_1) (envelope-from <info@...................................co.uk>) id 1anVej-0002Q5-Ra for info@...................................co.uk; Tue, 05 Apr 2016 14:24:54 -0400 Message-ID: <4E7F34BF4D05F4C6F7BA5C57A3758AF5@YY2RXP55> From: <info@..............................co.uk> To: <info@.....................................co.uk> Subject: You are owed $26,512 Date: 6 Apr 2016 06:58:30 +0600 MIME-Version: 1.0 Content-Type: multipart/alternative; boundary="----=_NextPart_000_002B_01D18FA2.065126A2" X-Priority: 3 X-MSMail-Priority: Normal Importance: Normal

Many spam emails hide their true source by using others addresses.

Some e-mail providers have the option to sort incoming mail. Contact your e-mail provider for help.
