when it says 'apearently to' then you have gotten a 'fake mail' .. someone is using your address in the 'from' field in the email format

we used to do this a lot in college .. was great fun :) .. but the security got a bit better after some years and it wasnt possible anymore for us on there. most providers dont allow this nowadays.

you could try to put a filter on your own address and when you receive email from yourself it is automatically deleted. but of course that way you will never be able to send yourself some emails from that address (be sure to test it thoroughly if you try something like that) not even a copy (cc) from a mail you are sending to someone else
