[Mimedefang] Enabling SURBL net tests only

[Stefan Schoeman]

Hi everyone,

I've finally got the SURBL tests working on my MIMEDefang Setup. However, my SpamAssassin scan
times are now quite badly affected with some scans taking up to 4 seconds. This is much much
slower than before. Now I see that SpamAssassin can perform many more tests such as razor, pyzor,
spamhaus and so on. I suspect that these tests are now ALSO being called by SpamAssassin whenever
a message is scanned. Is there any way that one can define which net tests SpamAssassin should
perform? I only really want SURBL at this stage, traditional RBL's I already do from sendmail.

Thanks,

STefan
