Spam Filtering Service

SpamExperts offers professional email security solutions such as incoming and outgoing email filtering as well as email archiving solutions. They're one of the most precise spam filtering solutions in the market. With the use of multiple filtering technologies such as advanced IP-reputation systems, a large number of message content classifiers manage to deliver nearly 100% filtering accuracy.

SpamExperts offers way more accurate email-filtering, it's using multiple technologies to decide if something should be marked as spam or not, where SpamAssassin, in general, are simpler and uses simpler methods to detect possible spam. SpamAssassin is also directly installed on your server and this can consume a lot of server resources which is not the case with SpamExperts and more importantly it isn't updated in real-time like SpamExperts.

SpamExperts uses a lot of different technologies to decide whether a specific email should be seen as spam or not.

There are a few stages how it performs filtering: pre-data, post-data and a stage in between these two.

The pre-data stage includes Connection rate limiting, IP Blacklist checking, destination domain verification, SMTP protocol compliance, sender address inspection, recipient validation checks, whitelist/blacklist of sender and/or recipients, recipient connection rate limit, SPF checks, content reputation feeds, bounce address tag validation as well as simple private signatures.

On the post-data stage, this includes validation of DKIM and DMARC, rules defined by a specific user, virus scanning, DNS and URI reputation checks, fingerprinting, statistical information about senders and heuristics defined by SpamExperts.

In between these two stages, there's also a direct feed looking at general IP reputation, if the sending IP is known for spending spam, and their sending history.

With most or all these metrics - the software will calculate a combined score - and depending on this score it will either accept the email or mark it as spam and thus putting it in the quarantine.

Some of the pre-data checks will result in dropping the emails before even reaching the post-data stage, this only happens if the sending server is poorly configured or being a part of one or more blacklists.

SpamExperts operate with a very high accuracy, this ensures that only legitimate emails go through but at the same time that the filter doesn't actually block legitimate emails unless something on the sending server isn't configured as it should.

In case most of your incoming email goes to spam are often due to if you're redirecting other email accounts outside your domain or hosting account towards your domain. This on a lot of mail servers rewrites the sender, which as a result will cause a lot of the filtering technologies to see the email as spam, most likely due to invalid SPF or DMARC records.

SpamExperts can prevent 99% of the spam emails addressed to your domain from reaching your inbox. The tests done by our team proved it to be very effective and that is all without making any changes to the default settings. Although there is no spam detection solution that works 100% perfectly, when this happens, you can flag such messages as spam so that SpamExperts marks them as a spam in future.

The delay is negligible. When our team did the tests, most of the messages were received within seconds of sending. SpamExperts has multiple servers that are spread around the world, so the location doesn't really come into the picture.

Yes. If you are a domain administrator, you can set up control panel access for users, or users can set it up themselves. Guidelines to access the control panel are included in the email which individual email users receive from SpamExperts when the first spam message is marked.

Whitelisting a recipient means that no email sent to that listed email address will be filtered by SpamExperts mechanism. Alternately, email sent to addresses that are blacklisted will be automatically rejected. If you want to make changes, using administrators tool, you can blacklist or whitelist recipients on the entire domain.

abuse@ and postmaster@ are not filtered by default, but if you need to make changes to it, you can.

Yes, an extensive log that shows all of the actions that SpamExperts takes is maintained. Make a note that there could be a short delay in the log updating, so if you are looking for the logs for a message that was sent some time ago, you may have to give the log a little time to update before the information is available.

No, when we activate SpamExperts for your domain, every email address on your domain is protected from spam.
