* i don't have mailman installed, but update.php tried to configure it
* i also fixed the check for doveadm in suse & fedora lib, but it seems my centos dovecot does not have "doveadm mount" subcommand, so i think the doveadm error will still exist
* on centos the 'receive_override_options = no_address_mappings' was added to postfix main.cf which leads to not working e-mail aliases/forwards
