Outbound Email Spam FilterHome / Security Articles / Outbound Email Spam Filter
Considering the consequences of being accidently blacklisted, it is a little surprising that not every email filtering solution has an outbound email spam filter by default. An outbound email spam filter can catch any email being sent from your organization that might be interpreted as spam by an over-zealous inbound email spam filter.
How could an email being sent from your organization be interpreted as spam? Easily. All it takes is an incorrectly spelled title in the subject line, or the overuse of spam-related words in the content of the email, and an inbound email spam filter with its parameters set very high could block the email and report your IP address to a Realtime Blackhole Agency.
Real-time Blackhole Agencies compile lists of known spammers. These lists are shared between all major email service providers (Outlook, Gmail, Yahoo, etc.), so it is possible that your emails could be blocked by the spam filters belonging to every one of your customers, suppliers and business associates. Normal service would only be resumed once your IP address was removed from a Realtime Blackhole List or added to each of your recipients´ white lists.
Although there may be a perfectly innocent reason for your organization´s IP address being blacklisted, there could be more sinister reasons as well. It may be the case that one of your organization´s employees is actually sending out spam email. This would not only be an abuse of their email privileges but would reflect badly on your organization.
It may also be the case that your organization´s IP address has been blacklisted because an email has been sent containing malware, or a link to a malware-infested website. This may not necessarily have occurred because your organization´s network is infected. It may because an employee has prepared a presentation on their malware-infested home computer and attached the file to a corporate email.
An outbound email spam filter can prevent these scenarios from happening. With outbound email filtering, all your organization´s emails are scanned for content that might be interpreted as spam and malicious software. Any spam emails or emails containing malware that are identified are quarantine and listed in a report for appropriate action to be taken by the system administrator.
