Most spam never reaches a BlastZone mailbox. Mail for the domains we host is screened by a dedicated filtering service before it is handed to our mail server, so junk is turned away at the door instead of piling up in your inbox.
What the filter does
- Checks every incoming message against current spam and virus signatures.
- Rejects mail sent to addresses that don’t exist on your domain, which stops dictionary attacks and much of the backscatter that hits small businesses.
- Blocks known bad senders before the message is accepted, so you never have to delete it.
Our filtering is provided by MX Guarddog, which works upstream of our servers to prevent spam from ever being delivered.
Something got through, or got stopped by mistake?
No filter is perfect. If a real message was blocked or a piece of junk slipped by, let us know and we’ll adjust it for your domain.
