I received an email in my spam folder that was from my email address but I did not send it to myself. As far as I know no one else has my password. What the heck is going on? How do I stop it? How do I find out who is doing this with my email address?

It’s just a trick the spammers are using, they don’t have your password. Most email software will allow spammers to change the “From:” or the “Reply to:” fields to any address they want.

“If you get spam email that you think is deceptive, forward it to [email protected] . The FTC uses the spam stored in this database to pursue law enforcement actions against people who send deceptive email.”

Send full headers of the message.

It will take awhile to see any progress but doing so will eventually help to reduce scam spam in your inbox.

One possible clue is how the sender is displayed in the Inbox or Spam box. In Yahoo if you have a real name entered in your account, if you send email to yourself that is the name that will display as the sender.
If the spammers are using their spam program to forge the recipient email address as the sender, you with see the email address displayed as the sender.

That is a trick spammers use to get you to open your mails. if you send mail to yourself, remember which ones they were, and do not open the others. Opening spam alerts the sender that your address is a valod one and they send you loads and loads more. You can not completely stop all spam, but you can help to put a big dent in it.
First, try not to open any of them, that only makes them send more and more to you.
Check mark them and click on ‘Spam,’ this should stop those addresses from being delivered to your inbox.
Use your spam guard and block address.
Look for the ‘Options’ link at upper right corner of mail screen and click on it
Options /mail options
Click on ‘spam’ in the list on the left.
Make sure spam guard is on, by checking in the little box.
Then in ‘Blocked Email Addresses,’ enter the E-mail address you wish blocked, in the box after ‘Add a blocked address’ and click on the ‘add’ button, then click on save changes at top left of screen.
You will never get mail from that address again.
This should help you to control your spam.
Other tips:
Do not ever open E-mail from people you do not know; and unless you are absolutely sure who it is from then treat them as spam.
Never, ever give out your account information or other personal information to anyone.
If you are on a site and you absolutely have to sign up for something, check the entire page to make sure you uncheck any lines wanting to send you any other info, notices, catalogs, ads, and the like.
Added detail:
Yes, spammers change one item in their addresses a lot, so you might try blocking the entire domain, by putting in
*@ thedomainyouwanttoblock.com
for instance: *@seeyou.com
Or, if they change the domain, instead of the company name you can block the name by putting in Imatheft_inc@*
Hope this helps
