Spam Filtering in Outlook
Microsoft Outlook is one of the largest email and most popular email clients for corporations. However, despite the popularity of the product, Outlook's spam filtering solution has proved ineffective by studies.
Why Does Microsoft Outlook Need An Additional Spam Filter Solution?
Office 365 spam filter offers a reasonable level of security, however, some businesses find it basic and lacking when it comes to highly-sophisticated cyber threats especially advanced and persistent spear-phishing attacks. Cyberattacks are ever-increasing, hackers are becoming more advanced with their techniques, hence organizations require an advanced threat protection solution to protect the organization's email.
How Does a Cloud Spam Filter Detect Email Spam?
Cloud-based spam filters use a number of different mechanisms to assess incoming emails to determine if they are genuine and should be delivered or if they are spam and should be quarantined. A cloud spam filter for Microsoft Outlook will first check the sender of the email against a global blacklist of known spammers. An advanced cloud spam filter such as SpamTitan will use run a host of other checks to check the authenticity of an email including:
- Bayesian Analysis: used to check the contents of emails for spam signatures, such as the use of non-standard characters and other idiosyncrasies.
- Greylisting: The practice of responding to the email server from which a message has been sent and requesting the message be resent. The time delay in responding to that request is a good indicator of whether the email is genuine. Most spammers perform huge runs of emails as part of their spam campaigns. Their mail servers are usually too busy to respond to these requests to resend emails. If the request is denied, the email is quarantined as spam. Greylisting ensures that spam sent from new IP addresses that have yet to be added to spam blacklists are also blocked.
Bayesian analysis and greylisting will greatly improve the effectiveness of a cloud spam filter for Microsoft Outlook.
