By default, our servers filter and scan all incoming mail versus a variety of DNSBL (DNS black list) spam filters. This includes, but is not limited to Spamcop.net, Spamhaus.org and others. Any mail sent from an IP address known by one of these services to be a spam source will bounce back to the sender as undeliverable with a message that has a web address (URL) with more information. We have no control over what IPs are blocked, but the services themselves are very reliable. Using them - they are on by default - will cut down on a lot of the spam you will see and receive. However, if you wish to opt out of the filtering for any reason, we can disable it for a specific email address on your domain, or for the entire domain.

Additionally, we also provide Spamassassasin, the popular spam filtering tool. To configure your Spamassassin settings, login to your webmail account, click on OPTIONS and then SPAM FILTERS.
