Caching results of hits to apply to several copies of same messages

[Antonio Guirado Puerta <an...@f-integra.org>]

Hello,

We are testing spamassassin 3.2.0 in a Linux Fedora box with QMAIL as
MTA. We would like to know if there is a module for caching the tests
results. We have seen than the same mail (identified always with the
same message-ID) is scanned multiples times (as many as RCPT TO command
are received). I think that this cache module that could work on memory
and store results during 5-10 min would allow reduce time processing.
Only general test (DNS, DCC, PYZOR ,etc... ) would be store in this
cache. Of course, the user preference should be applied to get the final
score but the results of the test (test hits) could be store. Any one
know if is it possible or are there a module similar?.

Thanks in advanced.

AFAIK, no such module exists in any generic way.

I know that MailScanner has its own result-cache database that works
somewhat like what you describe, but it doesn't apply individual
user_prefs and caches the entire SA result for the message.

As for the tests you want to cache, only DCC, PYZOR, etc would be
worthwhile. DNS is inherently self-caching if you've got a local DNS
server running.
