Spam filtering in mail server

As most of the email servers provide the anti-spam feature, the SM Smart Email solution does not include an extra spam filter for inbound emails. Instead, system administrators are encouraged to configure spam filters in their own email servers.

The following is an example for how to set up the anti-spam protection in Office 365:

Connection filtering checks the reputation of the sender before allowing a message to get through. You can create an allow list, or safe sender list, to make sure you receive every message sent to you from a specific IP address or IP address range. You can also create a list of IP addresses from which to block messages, called a block list.

Spam filtering checks for message characteristics consistent with spam. You can change what actions to take on messages identified as spam, and choose whether to filter messages written in specific languages, or sent from specific countries or regions. You can also turn on advanced spam filtering options if you want to pursue an aggressive approach to spam filtering. Additionally, you can configure end-user spam notifications to inform users when messages intended for them were sent to the quarantine instead. (Sending messages to the quarantine is one of the configurable actions.) From these notifications, end users can release false positives and report them to Microsoft for analysis.

For more details, refer to the Microsoft Office help.

If you are using an email server other than Office 365, refer to the official guide of your email server to set up the spam filters.
