As per advice from this list, I have been re-using my bayes databases on
several different servers running SA. On one of the servers though, the
database is not accepted. I re-transferred them several times over ssh,
to make sure they were not corrupted. The database files are in the
correct location, with correct permissions and owned by the correct user:
# ls -l /var/spool/spamd/bayes/
total 5912
-rw-rw-rw- 1 spamd spamd 1310720 2016-02-09 08:42 bayes_seen
-rw-rw-rw- 1 spamd spamd 4739072 2016-02-09 08:43 bayes_toks
The version of SA on both the donor and receiving servers is 3.4.1.
When I try to learn a new message on the receiving server (where I moved
the bayes files), I get the following error:
# su - spamd -c "/usr/bin/sa-learn -D --spam /New\ UnansweredSexHookup\
Request.eml"
