Dear OpenSuSE developers, on http://en.opensuse.org/AppArmor#Contribute i found info that all app-armor related fixes should be directed here, so after fighting some time with getting postfix to work with cyrus, i found that the following changes to postfix AppArmor profiles has to be added: in /etc/apparmor.d/usr.lib.postfix.local: /var/spool/postfix/private/lmtp rw, in /etc/apparmor.d/usr.lib.postfix.smtpd /usr/share/mysql/charsets/Index.xml r, in /etc/apparmor.d/usr.lib.postfix.master /usr/lib/postfix/lmtp prx, <--- not sure. in order to make local LMTP transport (via unix socket) work. and to enable mysql posfix plugin (thanks to Sandy Drobic who helped me to find this solution on suse-linux-e ) Probably some additional fixes might be required in order to make other mail_transports work as well (network lmtp socket, cyrus ?) Sincerelly, Vitaly.
