Anti Spam
Keep your inbox clean.
Using Astaro’s Mail Filtering, all of the spam and other unwanted email can be stopped before it gets delivered and clutters up mailboxes. A single Astaro can scan millions of messages per day for multiple domains, reducing employee confusion and frustration, and allowing them to work more efficiently.
The fight against spam is far from simple, but has a very simple goal: only valid, wanted messages should end up in an inbox. Spammers are clever, and constantly adjust their methods to bypass the filtering technology which stops their messages from being delivered and keeps them from getting paid. Astaro has several weapons in our Mail Filtering toolkit which can remove spam. Our primary engine uses a global pattern and fingerprinting technology to keep your inboxes clean.
Using Astaro, spam is identified by real-time communication with a network of millions of analyzers and participants which electronically scan and share the fingerprints of the mails they receive. With this approach, spam outbreaks are noticed within seconds, and Astaro receives live information as to which messages should be treated as spam, and which are valid. Our Anti-Spam engine doesn’t care what language the message is in, or even what it says inside. By tracking and identifying spam as it is launched and spread, the solution can scan at a much faster rate, with a far greater accuracy, than a traditional examination system where each message is totally inspected against an inflexible number of fixed rules.
