As of version 3.0, SpamAssassin supports [SURBL] natively.

-!! How to make SpamAssassin run on your local e-mail machine (with
[Evolution
] in mind)
-
-* get and install SpamAssassin, test that it works by piping a good email and a spam email through it
-* check that fetchmail(1) works, write a <tt>.fetchmailrc</tt> file
-* check that procmail(1) works, write a <tt>.procmailrc</tt> file
-* disable the regular pop mailboxes in Evolution
-* add a new "local delivery" mailbox to Evolution
-* write a tiny script I called <tt>getmail</tt> that does <tt>fetchmail -m procmail</tt> and make sure that it gets your email from the POP3 server correctly
-* add <tt>getmail</tt> to your crontab to run every 5 minutes
-* add a filter rule to Evolution: if specific header <tt>X-Spam-Flag = YES</tt>, drop the email in my Spam folder
-
-<tt>.fetchmailrc</tt>::
- <verbatim>
- poll mail.myisp.co.nz protocol POP3
- user "pop3user" password "secret" is user "localuser" here mda "/usr/bin/procmail";
- </verbatim>
-
-<tt>.procmailrc</tt>::
- <verbatim>
- # correct incoming messages for programs like Evolution and mail
- :0 fhw
- | formail -I "From " -a "From "
-
- :0fw
- | spamassassin
- </verbatim>
-
-<tt>~/bin/getmail</tt>::
- <verbatim>
- #!/bin/bash
- /usr/bin/fetchmail >> ~/log/fetchmail
- </verbatim>
-
-crontab::

- */5 * * * * /home/localuser/bin/getmail

-!! The ClamAV Plugin
-
-This plugin submits the entire email to a locally running [ClamAV] server for virus detection. If a virus is found, it returns a positive return code to indicate spam and sets the header <tt>X-Spam-Virus: Yes ($virusname)</tt>. If you'd like to sort virus emails to a separate folder, create a rule looking for this header.
-
-It requires
-* [ClamAV] installed so that scanning a mail with <tt>clamscan</tt> works
-* the [File::Scan::ClamAV | http://search.cpan.org/dist/File-Scan-ClamAV/] [Perl] module
-
-To install, create the files in <tt>/etc/mail/spamassassin/</tt>. You can adjust the default score of 10 in <tt>clamav.cf</tt> if you like. Restart the <tt>spamd</tt> daemon if you're using that, and you should be all set.

-You're using old format database files.
-
-The perl version change effected a change of the BDB version being used. The bayes_seen and bayes_toks fixes are BDB files and
-can be fixed by doing an db4.x_upgrade on them. sarge/hoary use Berkely DB 4.2, and you can install the db4.2-util package. with HTML

-----
-!! I'm running spamassassin from my MTA, and I get the error <tt>spam acl condition: cannot parse spamd output</tt> or similar.
-
-This occurs if you have upgraded perl, and not restarted spamd. Try restarting spamd and see if it solves the problem. It could also be a version mismatch, in which case you'll have to upgrade whichever process is calling spamassassin
