You could try to set NTTL to 0 (default: 1).
But, this are cached entries which had a score higher than REJECTLEVEL.
So, you should look first "why" they were REJECTed in the first place.
The default working scheme is such:
evaluate first time -
REJECET => SPAM cache with NTTL
DUNNO => HAM cache
resend after more than 30 seconds -
NTTL lowered, REJECT
resend after more than 30 seconds -
evaluate again - if REJECET => SPAM cache again
(In other words, the user must resend at least two times with an intervall
of 30 seconds in order to be re-evaluated again, this is to ensure, that a
human sits and reads at the other side).
The cache mechanism is merely a "feature" in order to reduce the bandwidth
for RBL providers and DNS.
If you want to disable caching completely set
$POSCACHESIZE = 0;
$CACHESIZE = 0;
Also, if you have that many "false positives" then you might want to increase
REJECTLEVEL to 4 or 5. Be aware that you explicitly want spam/viruses then in
order to tolerate misconfiguration even more.
