Developers of Sympa

[Sylvain Amrani <address@concealed>]

Hi,

For lists from a particular family, I need to warn senders when a bounce
occurs.

Anyone worked on this before ?

My first idea was to use MIME::Tools to recursively parse MIME::Entities
in the bounce, to find the original message and get its From: (and/or to
add a custom X-Sympa-Sender to messages of this family).

Unfortunately, looking at the bounce in the spool, I see that the
original List-Help, List-Subscribe and List-Unsubscribe in the message
attached to the bounce are set to "sympa@fqdn" !!! Is that the correct
behavior ? If so I've no way to be sure I get the correct attachment.

I didn't find in the source where List-* headers are changed in attachments.

Any help in understanding this would be appreciated !

Regards,
Sylvain.
