A message to a list member which fails in delivery and is returned to Mailman is treated as a bounce.
Bounce Processing
A message to a list member which fails in delivery and is returned to Mailman is treated as a bounce. 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. If a member address cannot be extracted, the bounce is discarded. If the member address can be extracted, the instance is logged by Mailman for that member, and after a certain threshold of bounces is reached for a particular member, the member is automatically unsubscribed from the list. Unless list administrators have specific reasons for wanting to handle bounce processing with different settings, we strongly recommend leaving the defaults for bounce processing as they are set upon initial list creation. For those interested, a more detailed description of how bounce processing occurs follows. Detailed description of bounce processing:- Mailman assesses the type of failure and assigns a score to it (either 0.5 or 1.0). Once a day, that score is added to the bounce-score for that member - so, if there are 10 failed mail messages in one day for an address, the maximum added to the score for that address is 1.0.
- Should mail begin to be delivered to the person again and Mailman be able to deliver messages without problem for a week, then the bounce score is reset to zero.
- When the bounce score goes over the threshold limit (the default is 5), the member's list membership is set to No mail, and Mailman attempts to notify the list member this action has happened and how to reverse the setting. The list administrator is also notified of this action.
- No further attempts to deliver messages will happen until the No mail setting is changed - either by the list administrator or by the list member.
- Mailman will attempt to notify the list member of the No mail setting 2 more times - at 7-day intervals. If, at the end of that time, the person's email address is still unreachable, the member's email address is removed from the list and the list administrator is notified that the person's email address has been removed from the list.
