Sympa allows bounces (non-delivery reports) management. This prevents list owners from receiving each bounce (1 per message sent to a bouncing subscriber) in their own mailbox. Without an automatic processing of bounces, list owners either become mad or just delete them without further attention.
Bounces are received at mylist-owner address, which should be sent to bouncequeue program through aliases :
\samplelist-owner: "|/home/sympa/bin/bouncequeue \samplelist"
bouncequeue (see 2.2, page ), stores bounces in a
~sympa/spool/bounce/ spool.
Bounces are then processed by bounced.pl daemon This daemon analyses bounces to find out what email addresses are concerned and what kind of error was generated. If bouncing addresses matche a subscriber's address, information are stored in Sympa database (in subscriber_table). Moreover, latest bounce itself is archived in bounce_path/mylist/email (where bounce_path is defined in a wwsympa.conf parameter and email is the user email address).
When reviewing a list, bouncing addresses are tagged as bouncing ; you may access further information such as : first and last bounces date, number of received bounces for the address, the last bounce itself.
Further development of Sympa should allow automatic deletion of bouncing addresses.
