I don't think that the -u option of sa-learn quite cuts it. According to the
man page, that's (simply) used for sql. You need to run in vpopmail's entire
environment (shell), so you should always run sa-learn using sudo:
sudo -u vpopmail -H sa-learn ...
Be sure to include the -H option, as that sets the home directory properly,
which is where the bayes databases reside. You need to do this in all 3
places where sa-learn is executed.
Also, in some instances (when sa-learn does a --force-expire at least), for
some odd reason sa-learn doesn't honor sudo entirely, and the bayes_toks
file ends up being owned by root. To keep this from being a problem, I'd add
the following to the end of your script:
chown vpopmail:vchkpw /home/vpopmail/.spamassassin/bayes_*
That should fix you up.
BTW, you might want to consider doing a --force-expire nightly as well, and
turn off auto-expire in the local.cf file. On some older hosts the
auto-expire can take long enough for an smtp session to time out, resulting
in a duplicate message being sent.
