This indicates a mistrained database, which means you have trained too
many spams or spam-like messages (commercial messages) as ham.
Proper training of spams should help. Just keep your spam (and
optionally ham) corpora for retraining in case you would drop the database.
I also recommend to abstain from training commercial mail (notices from
e-shops, companies you done business with etc) as ham, unless they
generate BAYES_999 score and you want it lower. I often train them as
spam so those give uncertain BAYES_50 result.
Those mails resemble spam too much to be used for training.
All,
The term "proper training" has always seemed a bit problematic to me.
That aside, experiencing an error trying attempting:
sa-learn -D --spam /var/mail/spamd/Cabinet.saved-spam
The last line shows:
***************
Learned tokens from 0 message(s) (1 message(s) examined)
ERROR: the Bayes learn function returned an error, please re-run with -D
for more information at /usr/bin/sa-learn line 500.
***************
Which may be permissions related. However, there seem to be some
errors/warning at the beginning, starting with:
***************

While this also suggests a permissions issue the only place I find
SpamCom.pm (even as root) is at:
"/usr/lib/perl5/vendor_perl/5.26.1/Mail/SpamAssassin/Plugin/SpamCop.pm",
which is not in the path sa-learn concocted when invoked.
Sorry if the formatting is weird or if this is useless information.
