Email Protection Service Features

Nearly every email protection service features a default spam email filtration system of some description. So why would a company have to apply a secondary email spam filter to block possible risks in addition to unwanted emails?

Probably the most compelling reasons would be the amount of spam email which bypasses this default security measure and the amount of time invested removing spam email.

The amount of spam email which evades detection by a default spam email filter might not appear to amount to a great deal, possibly four or five per employee each day. Nevertheless, each spam email requires four or five seconds to determine as well as delete. IfWhen you take all of this into account you can see that the total amount of time spent dealing with spam email equates to a huge amount of days of lost productivity every year.

Moreover, each spam email which evades detection could possibly be a phishing email, or maybe harbor malware and ransomware. A security conscious worker might be able to notice every harmful email as it arrives but, in just a system of a 1000 email users, the chance that an infected email is loaded in error increases a thousand fold. For these reasons it is essential to lower the amount of spam email as much as possible.

Most spam filtering solutions combine Real Time Blacklists as well as SURBL filters to identify spam emails from known sources of spam. In addition to this there can be receiver verification to reject email messages sent to non existent email accounts, and also to enable program administrators to generate Sender Policy Frameworks to be able to determine spoofed emails.

In the greylisting procedure, each new email is rejected and returned to the mail server where it originated with a request to be resent. In many instances, the e-mail is returned in just seconds. Spammers’ mail servers, however, are very busy and do not see this request. This means that the amount of spam email a company gets is reduced to the minimum amount possible.

Acceptable spam and user policies thresholds can be utilized as well as adjusted as required through the email spam filter’s user-friendly interface, through which whitelists can be set or blacklist certain email addresses as well as quarantine reports to recognize emails not forwarded to the intended recipients.

Email protection services can also be set up to review outbound emails. This could have several advantages for a company if a virus attacks the network, or if a cybercriminal compromises a company email account to send out spam & phishing emails.
