Relay of emails from the Internet to large volumes of addresses happen when the SMTP
email server permits third party relay of email messages. This is known as open relay.
By solving the overload of unwanted and unsolicited emails in the email server, the Spam
Filtering software does the important tasks of filtering and blocking before incoming emails
attempt to reach the email server.
The spam filtering software builds into the SMTP conversations as well as monitors the
incoming email traffic. When the software detects SPAM in the incoming mail, it automatically
rejects the mail by rejecting the sender or the recipient(s) of the email.
