Developers of Sympa

[Olivier Salaun - CRU <address@concealed>]

If I understand, you want to allow users to select filters to receive
only part of a mailing list traffis (the one they chose).

Sympa is almost able to meet your needs, let me explain you :

1/ Extending Sympa database structure
First have a look at 
http://www.sympa.org/doc/sympa/node8.html#SECTION00860000000000000000

You can extend either user_table or subscriber_table with your 'topics' field.
I guess extending subscriber_table would best suite you,
See http://www.sympa.org/doc/sympa/node6.html#db-additional-subscriber-fields

2/ Using news DB fields in scenarii

Now you have defined your 'topics' field in sympa.conf, you can access it
is scenarii as [subscriber->topics], like this :
        match([msg_body], /[subscriber->topics]/) smtp,md5 -> do_it


**BUT** Sympa has no scenario that tells if a message will be sent to a user 
(and
it would cost too much CPU, since it would be evaluated for each subscriber).
Therefore, you can't use scenarii for your needs, you should customize
List::distribute_msg() instead.

The feature you request in our development plans but we don't have time right
now.
