We employ the following features for spam protection:
- SpamAssassin; it is used globally on all the servers and can be additionally configured by means of cPanel, you will be able to choose the level of spam protection and blacklist/whitelist email addresses on your own;
- real-time block lists check, which automatically searches RBLs and rejects emails sent from blacklisted IP addresses;
- custom ACLs (Access Control Lists) with rules specifically designed for our mail servers;
- rate-limits, used to control email flow;
- ClamAV (antivirus system), which scans all the attachments so that emails that contain viruses could not go through.
