Along with all the other free resources included with your email account, we also offer SpamAssassin protection with your account. SpamAssassin is an automated solution that allows you to set a custom spam filtering score of 1-10. The higher you set this filtering score, the more strict your email spam filtering will be. You can also choose specific email addresses that you would like to block from sending to you.
You can also get advanced Barracuda Spam Filtering. When subscribing to Barracuda, each of your incoming emails will be evaluated before being delivered to you. If Barracuda determines that there's a high likelihood that an email is spam, If it's determined that an email is likely a spam message, Barracuda will prevent that email from being delivered. Each day, you will receive a list of all emails that weren't delivered. You can then determine whether or not you want to have that email sent. You can also whitelist specific email addresses so future emails are delivered to you without an issue.
