Filtering/storing outgoing mail...

[Andrea Giuliano <a giuliano iccu sbn it>]

Dear all,

I would like to filter, or at least just store, any outgoing mail 
message, not at a client level, but eventually at a lower level.

For instance, it would be enough to instruct postfix some way so that it 
stores outgoing messages permanently somewhere before sendind them. They 
usually stay for a while in /var/spool/mqueue, but when they are 
actually send are removed from there.

I don't want to rely on the client, because I could change it sometime 
(and I actually did it many times). I rather prefer a "system" solution. 
Clearly, a per-user solution would be better in order to prevent users 
to look at each other's mail, just like it happens with 
/var/spool/mail/<user>.

Many thanks in advance.
