It has it benefits over on-premises email filters inasmuch as a hosted email filter has fewer (if any) maintenance overheads, can easily be scaled up or down depending on the changing environment of your business, and is generally cheaper than an on-premises solution.

Most service providers host their email filtering services in high security data centers, have SLAs in place for when outages occur, and provide expert support and monitoring 24/7. For many SMBs, a hosted email filter is the ideal spam filtering solution, as it leverages cloud-based services to provide an enterprise-class solution for businesses on a tighter budget.

Does a Hosted Email Filtering Service Filter Emails Any Better?

That depends on the email filtering service you choose. Not all hosted email filtering services are the same, and some lack key mechanisms that (in our opinion) sacrifice online security for performance. Naturally, the filtering settings applied by a system administrator will also influence how effective a hosted email filter is at protecting a business from email-borne threats as well.

For this reason, the best hosted email filtering services are those which are easy to use. A hosted email filter can have all the “granularity” in the world to apply different settings to different users depending on their roles; but if it is too complicated to apply different settings to different users - and gaps in the filtering parameters allow spam emails to enter the business - the high level of granularity is worthless.

Going Back to the Online Security vs Performance Issue

When you use a cloud-based email filtering service, the filtering process is conducted in the cloud - eliminating any strain on the business´s CPU or mail server. Therefore, it is difficult to comprehend why some service providers omit to include resource-intensive features such as greylisting and outbound filtering in their services - unless it is to save resources at their end.

Greylisting in particular is a very important online security mechanism. Most email filtering services use SURBL filters to block the delivery of emails from IP addresses from which spam email is known to have originated. What greylisting does is return every email and request it is sent again. Spammers´ servers are usually too busy to respond to the request, so the email never gets resent.

In this way, a hosted email filter with greylisting prevents the delivery of spam emails from not-yet-known sources of spam - giving businesses a higher level of protection against email-borne threats such as phishing, malware and ransomware without any loss of network performance. The greylisting process can create short delays in email receipt, which is why we also include a whitelisting feature in our hosted email filter in order to allow emails from trusted senders to bypass the greylisting security mechanism.

Hear from our customers

Provides good security, saves me an hour a day, and is cost-effective

It's very easy to configure to block and greylist a lot of things that we see coming in as a vector for email attacks. So, it gives us much better security overall, as well as some time savings on the administration side.

Highly accurate, reduces the number of service calls, and has a fair price

It has reduced the risk of getting viruses from emails by almost a hundred percent. We are giving services to hundreds of companies, and it makes our work a lot easier when SpamTitan is filtering threats.

CTO, Genie Support

Has the ability to easily see what was blocked, enabling users to restore emails they were expecting with the click of a button

It reduces email clutter, improving employee productivity. It does what it says it does. It reduces spam by quite a bit above and beyond the Office 365 built-in spam filter. One aspect our clients liked about SpamTitan was the ability to easily see what was blocked.

Frequently Asked Questions (FAQs)

What advantages does a hosted email filter have over an on-premises solution?

The advantages a hosted email filter has over an on-premises solution include the lack of maintenance overheads, scalability, and cost-effectiveness. However, when choosing between a hosted email filter and an on-premises solution, it is important not to overlook the ease of use and configuration capabilities of either solution.

Where do most service providers host their remote email filtering services?

Most service providers host their remote email filtering services in the cloud. This is because the cloud offers more security, scalability, and redundancy than a private data center and has the mechanisms to support user authentication, fluctuating volumes of users, and high-percentage Service Level Agreements.

Why is a hosted email filter considered suitable for SMBs?

A hosted email filter is considered suitable for SMBs because the filter leverages cloud-based services to provide an enterprise-class solution at a more affordable price. The scalability, ease of use, and reduced maintenance costs make it particularly appealing for businesses operating on a tighter budget, while offering quality protection against email threats.

Do all hosted email filtering services have the same capabilities?

Not all hosted email filtering services have the same capabilities and it is important for businesses to compare solutions in order to avoid those that sacrifice security for speed or those that are packed with capabilities a business will pay for but never use. Thereafter, factors such as ease of use and configuration should take priority over price.

Why is Greylisting an important feature for email security?

Greylisting is an important feature for email security because most email filtering mechanisms work retrospectively (i.e., block lists and ML capabilities are based on previous spam history). Greylisting helps reduce spam from previously unknown sources - and previously unknown patterns of spam - by returning all emails from non-whitelisted sources to their originating servers.

Returned emails are accompanied with a request for the emails to be resubmitted; but, due the volume of emails returned to spammers’ servers (via all filtering processes), the “retry” function is usually disabled to preserve bandwidth for fresh spam. Consequently, greylisted spam emails are rarely returned to the intended destination mail server.

What is the purpose of the whitelisting feature in an email filter?

The purpose of the whitelisting feature in an email filter is to allow emails from trusted sources to bypass some of the filter’s mechanisms, which accelerates the delivery of the emails. While a useful feature to prevent delays, whitelisting should not be used too widely in case the originating email account is compromised and used to send email-borne threats.
