SpamExperts applies its proven, self-healing, intelligent technologies to eliminate unwanted email messages before they reach in your network.
By using SpamExperts Inbound Filter, you create additional redundancy and continuity of the email delivery process. When the destination server is unavailable, SpamExperts filtering systems place messages in a queue to be delivered when the server is available.
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.
