Hi,
Thanks for your help. I think we're getting closer to it:
I get some log entries now, but no further processing is done (see
below, the blacklist entry is not retrieved). I also don't observe any
call to the database in the mysql log.
These are the entries I get (slightly anonymised):

("$GLOBAL" is the name under which I have defined my rules in the
spamassassin db, and I've simply mapped all email addresses to this
global identifier in the config file of amavis, as follows:
@sa_userconf_maps = (
{
'.*' => 'sql:',
}
);
@sa_username_maps = new_RE (
[ '.*' => '$GLOBAL' ]
);
)
So I suppose the reason is that spamassassin's user_scores_dsn ruleset
in /etc/spamassassin/local.cf is not considered. Might it be reading
from the wrong file, or not have the permission etc.?
(Does anyone know how to figure out which spamassassin config file
amavis uses?)
I think this is a very probable cause since everything works (also the
blacklisting) when sending my email via spamc on the command line.
I'd be more than happy if anyone could point me in the right direction.
I've spent hours fixing this, without success.
Thanks a lot,
S.

You could increase the amavis debug log to maximum and you should look for @sa_username_maps to determine if the amavis log is correctly determining the SA username, be prepared for a lot of debug information but I do know that amavisd refers to the @sa*.* config options in the debug, so you could always look for those.
