Was my account hacked? In all likelihood, no. If you are receiving emails to your domain (even bounce messages) which are addressed to non existant users, you probably have a catchall setup on your domain. A catchall is a way for the mail server (or MTA) to route emails which are addressed to invalid accounts at your domain, to a specific default inbox. This will be very noticable if a spammer is forging return addresses to your domain ( which is not difficult to do at all). To alleviate this, we recommend you disable your catchall. To disable your catchall, simply follow these steps:

1) Login to your cpanel account
2) Click on the mail icon
3) Click on default address
4) For each domain, there will be a box with the value of the default address for this domain. Enter ":fail: No such user here" in the box

And that will help prevent your account from accepting emails addressed to non existant accounts.
