If you’re using an AOL email address, you may not be. AOL has mentioned, off the record, that they will be bumping any email that has generic Apache headers. That generally means, any mail that is sent using PHP’s mail() function.

This affects WordPress users because WordPress makes use of the mail function to send the password, comment notifications, and other administrative emails. If you’re using AOL, you may never receive it.

Generic Apache headers are different than the ‘From:’ address - if you look closely at message headers of mail sent with the PHP mail function, you may notice Return-path: <nobody@yourhost.com>.

Right now, there is a work around, but this involves modifying core WordPress files and this problem may affect more than just your WordPress blog.

The recommendation is simply to use another email account. You can sign up with Gmail or Yahoo! for free, but the better option would be to create an email address with your domain name.

It looks more professional and if your host supports it, you can have the mail forwarded to another email address.
