Where to find score-settings for multi.surbl.org lists

[Martin Lyberg]

Hi!

I recently installed Mailscanner and spamassassin on debian. I haven't configured it to use multi.surbl.org lists, but when i send a test mail with a testlink, i can see that it's catched as spam, just like it should:

MailScanner-SpamCheck: spam, SpamAssassin (score=9.303,
    required 5, HTML_MESSAGE 0.00, RCVD_BY_IP 0.02, URIBL_AB_SURBL 2.01,
    URIBL_OB_SURBL 2.00, URIBL_PH_SURBL 0.84, URIBL_SC_SURBL 3.90,
    URIBL_WS_SURBL 0.54)

My question is, where can i set the score-settings and remove/add surbl-lists? I've checked all config-files, but can't find the settings anywhere.

Is it enabled in spamassasin by default? Where can i find it?

I'm using the following versions:

MailScanner 4.41.3
SpamAssassin version 3.0.3
  running on Perl version 5.8.4
Postfix 2.1.5

Thanks in advance.
