How will BL-Monitor improve performance of my email network?

Fine tuning your email filter through the selection of the most effective DNSBL servers will improve its ability to receive inbound email efficiently.

Also, DNSBL servers that do not blacklist IP addresses where your spam originates are of little use for your email filtering. Choosing another DNSBL server will improve the performance of your filter, saving resources and speeding mail delivery.

Use BL-Monitor Periodically To...
	Watch for DNSBL servers that stop responding if too many queries are received from the same source over a set period
	Verify that Free DNSBL servers are still on-line or have not changed to a paid subscription model
	Check for good response times of DNSBL servers and verify that they have not come under denial-of-service attacks
	Examine the popularity of free DNSBL servers that may exceed their capacity to keep up with the growing demand resulting in slowing response over time.
