With SpamRazer filtering, greylisting, IP reputation filtering, Bayesian filtering and other advanced anti-spam technologies, our spam capture rate is over 99%. GFI MailEssentials also has an enviable low rate of false positives ensuring the safe delivery of important emails. Greylisting Greylisting is an anti-spam technique used to identify spam emails originating from non-RFC compliant mail servers (which are often utilized by spammers). For each new SMTP transmission, GFI MailEssentials records the sender, recipient and sending mail server's IP address (aka triplet) and rejects any emails with a temporary failure message. Compliant email servers try and resend the message after a few minutes – this causes their triplet to be confirmed and connections with the same triplet are no longer rejected. Non-compliant mail servers do not try to resend the message. Spam Quarantining The administrator can select to quarantine spam emails. Spam emails are stored in a database and are automatically deleted after a pre-defined period of time. The administrator can also select to send a spam digest with information on quarantined emails. From the spam digest, users can review their spam emails, and approve them as required. The administrator is allowed full access to the quarantined emails.
