Abuse and Blacklist Prevention
	Acceptable Use Policy ("AUP") Link
	SPAM Throttling

Serious measures are taken to keep spammers from using our email hosting system to send mail and to keep our system out of the anti-spam blacklists. Acceptable Use Policy compliance is strongly enforced in order to maintain the integrity of the email service for the benefit of all customers.

Monitoring systems detect when a customer tries to send out an unauthorized bulk mailing, and cuts it off before it is too late, alerting our engineers, who then contact the customer.

Also, WEBPRO International's email server IP addresses are checked against the anti-spam blacklists hourly. In the rare case that one of our IP's becomes blacklisted, engineers receive an alert from the monitoring system.

Immediately, our engineers take action to diagnose and stop whatever caused the blacklisting to occur. During this time, the IP address that was blacklisted is removed from use so that no outgoing mail is sent from it. If an entire range of IP addresses become blacklisted, fallback routing is used to route mail through an alternate cluster of SMTP servers with clean IP's. Once the issue has been resolved, we contact the blacklisting organization in order to get the IP address removed from the blacklist.

WEBPRO will attempt every precautionary measure to validate the integrity and intentions of all of it's customers email business practices. If a customer has been informed of an email violation and fails to take steps to remedy the situation, then the Customer can be discharged and email services terminated immediately.

SPAM Throttling

A distributed database tracks real-time information about connections to our servers and where spam and viruses are currently being sent from. This information is used to rate-limit mail from likely spammers and from emerging spam and virus sources. Rate-limiting is a safe way to reduce spam because mail is never blocked. Instead, mail is allowed through, but at a much lower rate. This permits legitimate mail to be delivered, while slowing down high-volume spammers.

This system also protects the servers from denial of service ("DoS") attacks by limiting the number of concurrent and successive connections third-party servers can make.
