How can I get rid of spam? (unsolicited bulk emails / UBE)

There are a few things you can do. One of which is to remove the default line in the forwardings section of your control panel.

This will make it so that all emails sent to any address that's not already specifically pointed to a pop account, or forwarded elsewhere by your control panel, will simply bounce.

This will prevent you from having to deal with spam sent to addresses you never use. (Spammers frequently send spam to commonly used email addresses such as sales/support/contact/info/etc... as well as common proper names)

This of course means you'd have to setup pop accounts and/or forwardings for whatever you do want to use, and that you'd lose the ability to use the catch all feature that will make sure you get any email that ends in your domain name, but it may be worth it to you.

You can setup the spam filter included with your account through your control panel (login and click on "Spam Filter" in the menu to your left) but even the best spam filters can never completely stop spam.

If you're serious about stopping the spam, you may want to look into a service such as SpamArrest as this type of service is currently the only way to rid yourself of spam completely.
