An email spam server solution is an anti-spam and user-friendly system for email filtering on your network.
Using this improves a server’s spam detection rate and decreases any business’ exposure to email threats including phishing, malware and ransomware. An Email Spam Server is easy to set up, with installation possible as a virtual appliance or by redirecting the mail server’s MX Record to any cloud anti-spam service from an SaaS supplier.
Once created, it will filter all incoming emails at the server level rather than at a client level, which means less maintenance than a client level solution while giving network administrators a higher level of control over all email activity and the amount of threats being blocked by this server.
The vast majority of email services may incorporate some degree of email filtering, but with the huge levels of spam and phishing emails registered by businesses day-to-day, it is rarely sufficient in the face of cyber attacks. Normally, default anti-spam servers block from 95% to 97% of spam – and in a big corporation this results in hundreds of spam emails and possible malware or ransomware issues are not spotted every day. Even at the highest levels of spam detection, there is cause for concern with such a spam email service in place.
Hackers are higher in numbers and have more sophisticated campaigns than ever to deliver harmful ransomware and malware-infused messages. An Email Spam Server is the difference between such attacks being spotted and stopped or being delivered to a user’s mailbox. Only one click on a maliciously composed URL sent by a hacker is all it takes for such attacks to infiltrate your network.
Using a third-party email filtering solution with more advanced features and anti-spam mechanisms than the default provided with most solutions is one of the wisest moves that you will make. A dedicated and focused Email Spam Service will spot a greater number of spam issues and other threats while majorly boosting improving your security position. With an advanced server spam filter or cloud-based filtering solution you can minimize the amount of threatening emails that arrive in inboxes before they cause any harm.
Most default email services employ Real-time Blackhole Lists (RBL’s) and SUBRL filters to prevent spam infecting your network. These compare IP addresses in databases with lists of known IP addresses where spam has been known to be launched from. Thus, the reason a threatening email evades detection is likely that it has originated in a new location, not previously used for spam.
Email spam servers employ a process called greylisting to target spam sent from unknown sources. It does this by returning suspicious emails back to its original server with a request for it to be re-sent. Most mail servers reply very quickly and the emails are returned. However, they also go through a range of secondary tests to determine their legitimacy. However, Greylisting can cause a small delay in the receiving of messages, delay which can be prevented if trusted users are added to a whitelist. This will guarantee their messages are received without delay.
An email spam server solution will likely be too busy sending these spam emails to respond to a resend request so emails are unlikely to be returned or will be delayed sustainably. Using this process, an email spam server increases spam detection rate from 99% to near 100% – substantially reducing the amount of harmful and malicious messages being crafted and sent every single day.
