Spam Filter for Exchange 2010 (2022)

Opinions differ over what might be the ideal spam filter for Exchange 2010. Some businesses would be happy with the automatic updates that used to be available with Exchange 2003. Others would like the operation of the Exchange 2010 email filter to be less complicated. Most would likely settle for an Exchange 2010 spam filter that was effective at preventing spam.

The main problem with the built in anti spam for Exchange 2010 (and for subsequent versions of Exchange) is that the anti spam mechanisms work retrospectively. Microsoft´s “real-time block lists” are only updated when businesses report spam; and – if you forget to do a manual software update – it could be weeks until the “real-time block list” is blocking the most recent sources of spam.

Because the spam filter for Exchange 2010 works retrospectively, you are unlikely ever to enjoy a spam-free environment – even if you paid for the automatic update feature (via Forefront Protection). This is because, once their IP addresses have been blocked, spammers simply set up using a new IP address and continue sending spam emails. However, there is a solution – Greylisting.

Greylisting and Anti Spam for Exchange 2010

Opinions also differ over the benefits of Greylisting because the process involves returning all incoming emails to their originating with a request they are resent. This process takes time, and can delay the receipt of business-critical emails, but it does identify spam from previously unknown sources – minimizing the amount of spam that evades detection and the associated risks.

Compared to the built in anti spam for Exchange 2010, an email filter with Greylisting is far more effective at preventing spam being delivered to users´ mailboxes. It not only reduces the risks associated with spam email (phishing, malware, ransomware, etc.), but also reduces the amount of time users spend identifying, reporting and deleting the spam emails they receive – thus increasing productivity.

An Exchange 2010 spam filter with Greylisting usually also has a whitelisting feature system administrators can apply with the click of a mouse to allow business-critical emails from trusted sources to bypass the filtering mechanisms and prevent delayed deliveries. This feature should be used sparingly however, as trusted email accounts can be compromised by spammers and used to send spam emails.

Other Features a Spam Filter for Exchange 2010 Should Have

While on the subject of email accounts being compromised by spammers, an ideal feature a spam filter for Exchange 2010 should have is outbound scanning. Outbound scanning monitors the spam content of emails being sent from your business to ensure they do not fall below preset Spam Confidence Levels. The importance of this feature is that, if a business email account is compromised and used for sending spam, your IP address could be identified as a source of spam and added to the real-time block list.

Other features a spam filter for Exchange 2010 should have include antivirus scanning – for both inbound and outbound emails – and SUBRL filtering. As well as comparing inbound emails against a list of IP addresses from which spam is known to have originated, SUBRL filtering compares links within emails against lists of URLs found in unsolicited emails. It is due to SUBRL filtering we know 99.5% of websites with the word “PayPal” in their URL have been published for the purpose of obtaining log in credentials.

Naturally a spam filter for Exchange 2010 should have automatic updates, but equally important it should be easy to administer. The Exchange 2010 spam filter is unnecessarily complicated and it is difficult to apply different policies to different users, user groups or domains. As a result, Spam Confidence Levels can either be set too low, allowing spam to evade detection, or too high – resulting in emails from genuine senders being quarantined (“false positives”).

Users of Microsoft Exchange/Office 365 can improve their defenses against sophisticated email threats with SpamTitan. SpamTitan uses advanced predictive techniques to identify rapidly evolving email threats. These mechanisms include Bayesian analysis, machine learning, and heuristics, which are lacking in Exchange and Office 365. These mechanisms are superior to those of Exchange Online Protection and will maximize the probability of email threats being detected and quarantined, rather than being delivered to susceptible end users.

Exchange 2010 Spam Filter: FAQ

If Microsoft Exchange 2003 has inbuilt spam filters, why is a third part filter needed?

Even though Microsoft Exchange 2003 has got inbuilt spam filters that help to prevent spam emails from reaching a user’s inbox, they are not perfect. Significant volumes of spam are sent every day, so even if a small percentage of spam emails escape filters, it can still clog inboxes and slow productivity. Microsoft’s blacklists are partially based on what users report to be spam emails, so if a user receives an unsolicited email, but does not report it as spam, the IP address will not end up on the blacklist. Third-party spam filters use more advanced techniques, such as SURBL filtering, to ensure up-to-date detection of spam emails.

(Video) Installing an Exchange Server spam filter

How is Greylisting different from blacklisting?

Blacklists are lists of IP addresses known to be associated with spam emails. A spam filter that is based on a blacklist will automatically block any emails coming from one of those email addresses. Greylists temporarily block emails that may be suspicious but do not come from blacklisted senders. This can protect the user from new sources of spam.

Can spam filters prevent legitimate emails from being sent or received?

Some spam filters may be over-sensitive, and block genuine emails from reaching the intended recipient. This has obvious consequences for both business relations and productivity. However, this will be rare with good spam filters. To help guard against this, “whitelists” can be established, which contain the addresses of trusted senders whose emails should not be blocked.

What is outbound scanning?

It may be the case that rather than being the recipient of spam, a legitimate email address may become the source of it. This can happen if the user is the victim of a phishing attack or has downloaded malware. Outbound spam detection checks if the emails sent from your accounts are spam emails. This can help to prevent further malware attacks but also save the business’s reputation as they do not pass malware on to clients.
