Right.
Thank you Mark and Bailey,
I have upgraded the spamassasin to 3.3.2, now i dont see the initial
error message and can see that amavis is invoking the multiple
rulesets of SA and also the corresponding scores are set for emails.
Does SA increases the load on the system ? Are they any tweaking
guides to enable only specific rules in SA and not all?
The main thing to watch for with SA is memory usage. Each Amavis
process will load up all of the SA rules, so they can use a fair chunk
of RAM. Make sure to tweak the max number of processes in the Amavis
config so that you don't go into swap when the system gets busy.
SA is already tuned as much as possible for general use. Unless you
have specific problems, it is not usually a good idea to disable any of
the default rules. Most of the "tweaks" you will find for SA involve
loading extra rules. This causes SA to use more resources, but it can
increase the accuracy.
