Thanks, that was quick. However :



1. the avahi changes need more cooking :

rpm -Uvh selinux-policy-targeted-1.27.2-9.noarch.rpm

/var/lib is already defined in
/etc/selinux/targeted/contexts/files/file_contexts,
/usr/sbin/genhomedircon will not create a new context.



2. procmail still has trouble invoquing spamc

3. But squirrelmail now works -> the postfix postdrop problem is fixed.
Thank you !

(I'm running with a tail on /var/log/audit/audit.log in a term now)
