The administrator is allowed full access to the quarantined emails.
From the spam digest, users can review their spam emails, and approve them as required. The administrator can also select to send a spam digest with information on quarantined emails. Spam emails are stored in a database and are automatically deleted after a pre-defined period of time. Spam Quarantining The administrator can select to quarantine spam emails. Non-compliant mail servers do not try to resend the 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. 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. 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). GFI MailEssentials also has an enviable low rate of false positives ensuring the safe delivery of important emails. With SpamRazer filtering, greylisting, IP reputation filtering, Bayesian filtering and other advanced anti-spam technologies, our spam capture rate is over 99%.
Not only will administrators benefit from out-of-the-box filtering but they will also gain protection from each new attack without the need to tweak GFI MailEssentials. Due to frequent updates, SpamRazer needs no tweaking to be fully effective in filtering the latest spam attacks. SpamRazer™ - A Powerful Anti-spam Engine SpamRazer is a powerful anti-spam engine that has been designed for ease-of-use.
