skipping expire
This means that your Bayes database doesn't have enough
tokens in it yet
to do a proper expiry. Let your database grow a little more
before
trying to prune it--it clearly doesn't need it yet. Once a
week should
be more than sufficient (and in any case the expire function
won't work
any more often than once every 24 hours).
The other thing to note is that by default, SpamAssassin
tries to expire
its own Bayes tokens every time a new email is
processed--i.e. it
expires in real time. On a low-traffic site this is
generally fine, and
it does a good job of keeping the database clean, such that
running a
manual expiry process like this only needs to be done every
few months
to tidy things up.
On busier sites, though, that real-time token expiry means
extra work
for the database and can slow transactions down a fair bit,
so it's
better to disable that feature and just schedule a cron job
to run a
forced expiry process once a day at a more optimal time. To
do this,
set "bayes_auto_expire 0" in your local.cf file,
and schedule a daily
cron job to run "maiadbtool.pl --expire-bayes".
