Not sure if any knows the answer or remedy :

Whether I use my iphone 5s or my windows xp- outlook6 or windows 10- live mail all my email I send under my personal email address i always get the 'sent' email sent not only to the recipient but also back to me ,
I get the same email I sent to my own account -- back..
Never had this happen before in the 20 years of sending email only the past few months .. should I contact my IP provider as it is their @shaw that is the culprit not gmail or any other other IP browser.

obviously something is turned on ...

but where ?
