If you have an email account from Yahoo you may be finding that people that you know are suddenly receiving emails from what looks like you.
These emails however which are usually spam or porn in some cases look like they have been generated from a third party provider and will have your name in the front of the email.
For example firstname.lastname@example.org but will be picked up by your Yahoo account and delivered when it is not even your address or from Yahoo.It looks like a catchall implementation has taken place with Yahoo capturing any email that resembles your name.
So what do you do?
Cancel your Yahoo email account seems to be the only way currently until Yahoo fixes this.
