Well my mailchain is as follows:
fetchmail->procmail->clamassassin(using clamd)->spamassassin->dovecot
clamd and spamd are both started from init.d scripts if that's what this
means...

Hmmm... I was about to say that nothing is run as root WRT spamassassin
or spamd, but then I looked at the avcs. It seems that razor is the
offender here:
avc: denied { getattr } for pid=2200 comm="spamd"
path="/root/.razor/razor-agent.conf"
(and several others like it)
I don't know if razor can be installed by a non-root user. If not, can I
(should I?) just do what you suggest below?

Could this be /root/.razor/ ?

Does this make the command:
# semanage fcontext -a -t spamassassin_home_t '/root/.razor(/.*)?'
# restorecon -R -v /root
?

I will look into this tomorrow...
Thank you very much for your help so far.
