What is a dispose threshold?
The dispose threshold is the score at which email will be disposed of and you will not see it in your email inbox or sideline display. This threshold allows you to avoid dealing with email in your sidelined list that is almost certain to be spam. The dispose threshold can be set from 11 to 50 or left blank. If left blank, a user will use the domain dispose threshold. A blank domain dispose threshold will use the default value of 20. Statistically, a setting of 20 will typically dispose about the worst 15% of your junk email. With the dispose threshold set to 15 you can expect to avoid roughly the worst 25% of your email.
