This numerical qualifier is then added to a database of other spam signatures. Administrators can use signature matching software to protect their inbox from spam. When the database is installed on their mail server, all spam email signatures are blocked from their inbox. These databases are updated frequently to protect from the most recent spam addresses. Signature matching is another spam filtering feature that protects your inbox.

This text also registers a sender’s security signatures. Spam filtering models analyze this information to determine where the email came from.

Rule Based Filtering
