Here's an overview of how it works: + +<p> +When a bounce is received, Mailman tries to extract two pieces of +information from the message: the address of the member the message +was intended for, and the severity of the problem causing the bounce. +The severity can be either <em>hard</em> for fatal errors, or +<em>soft</em> for transient errors. When in doubt, a hard severity is +used. + +<p> +If no member address can be extracted from the bounce, then the bounce +message is usually discarded. Every member has a <em>bounce score</em>, +initialized at zero, and every time we encounter a bounce from a +member we increment that member's score. Hard bounces increment by 1 +while soft bounces increment by 0.5. We only increment the bounce +score once per day, so even if we receive ten hard bounces from a +member per day, their score will increase by only 1 for that day. + +<p> +When a member's bounce score is greater than the <em>bounce score +threshold</em> (see below), the member's subscription is disabled. Once +disabled, the member will not receive any postings from the list until +their membership is explicitly re-enabled, either by the list +administrator or the user. However, they will receive occasional +reminders that their membership has been disabled, and these reminders +will include information about how to re-enable their membership. You +can control both the number of reminders the member will receive and +the frequency with which these reminders are sent. + +<p> +There is one other important configuration variable; after a certain +period of time - during which no bounces from the member are received +- the bounce information is considered stale and discarded. Thus by +adjusting this value, and the score threshold, you can control how +quickly bouncing members are disabled. You should tune both of these +to the frequency and traffic volume of your list. + +<p> +<dl> +<dt><strong>bounce_processing</strong></dt> +<dd>Specifies whether or not this list should do automatic bounce + processing. + +<p> +</dd> +<dt><strong>bounce_score_threshold</strong></dt> +<dd>This is the bounce score above which a member's subscription will + be automatically disabled.
