hi folks --- everything seems working like chicken. I'm loving SA so far.
However, I would like to disable all network tests (each mail takes ~10
seconds!). Except that I dunno how to do it the neat way.
Will the tests be disabled if their score is 0? I know that would lead
into disabling the effect of a rule on the decision making of SA (i.e.
Spam/Ham marking), but would SA exclude them from running too?
I need to disable all BLs, DNS queries, and anything that uses the
internet. Kindly advise.
Thank you guys -- May OOP Raise and Shine!

Please consider that spamassassin is CRIPPLED without the network tests.
If it is taking 10 seconds per message then you likely have some kind
of serious misconfiguration. The first likely culprit is your DNS
server is not good. Several times in past years I've had to stop using
my ISP's (or data center's!) official DNS servers because they were
simply not capable of handling the load of spamassassin. In such cases
I run pdns-recursor on each Spamassassin server directly, and set
/etc/resolv.conf to use 127.0.0.1 as the DNS resolver.
After you have switched to a known good DNS server, do the following to
diagnose the network tests.
1) Save a single spam message as a flat file, with headers and body
intact. If your folders are Maildir format then a single file in your
directory tree is suitable for this purpose.
2) cat FILE | spamassassin -D
3) Copy the entire output and paste into a text editor.
4) Look at the lines near the bottom for "async: timing:" Those are
followed by a number of seconds that an individual DNS request took to
respond. All of these numbers are typically between 0 and 3 seconds on
my server. If you have much larger numbers or some queries are timing
out entirely, then you may have further issues with your DNS server, or
you may have been blocked from queries because you have exceeded free
usage limits.
