This udpate fixes the following issue with yast2-mail:
- bnc#800788: fixed hang of the system after the ag_postfix_mastercf process is killed by kernel, when saving mail server settings with Yast "Mail Server" module
- Mark permissions files as %config
- The ldap tables was not proper. All functions for forwarding and delivery must be placed in alias_maps and not in virtual_alias_map. Forwarding or delivering actions in virtual_alias_map may cause mail loops.
