A spam filter is a software app that runs on a POP3/IMAP mail server and keeps track of all inbound emails so as to impede any unrequested ones from reaching a particular mailbox. Several instances of such emails would be: offers for pills or money, false bank notifications or email attachments that contain malware sent with the intention to damage your PC. Email filters usually examine the content of an email and in case they come across some keywords or other dubious content, they either delete the email or deliver it to the Junk/Spam folder instead of the Inbox folder. Some companies mix their own filters with up-to-the-minute databases from spam-tracking organizations, so as to guarantee better security for their customers. Such databases contain patterns, email server IPs and other information about spam email messages recently revealed by these organizations.
Spam Filters in Shared Hosting
If you order a shared hosting package from our company and if you take advantage of our mail services, you will be able to activate spam filters for any of the mailboxes that you create from the Email Manager section of your Hepsia Control Panel. With just a few clicks of the mouse, you can select between five different levels of security. In case you start receiving spam, you can start with the lowest level and then gradually increase the level until you stop getting spam. We make use of one of the best and most popular spam filters available called SpamAssassin. It examines the header and the body of every email message that you receive and calculates a spam score, based on which it either erases a given message or permits it to enter your inbox. The Hepsia Control Panel will also permit you to create custom spam filters and either delete unsolicited email messages or re-send them to a third-party email address such as spam@domain.com where you can check them again at a later time.
