I updated the sogo.conf, but it doesn't work. for example i have 10 mail addresses and i don't want to be seen boss@domain.com in global address book.  But i want all addresses to see eachother's mail addresses but the boss' mail address.

how can i do that ?

I want a certain mail address not to be seen by other users at the same domain on the global address book.

my full sogo.conf is below;

            isAddressBook = NO;
            //displayName = "Global Address Book";

Hello Sir

Unfortunately, although i did as you specified, but if i set first  in SOgoUsersSources block isAddressBook is NO.
second block is set canAuthenticate = NO' and 'isAddressBook = YES'
after sogo service restarted, i can not login at sogo loginpage.

my filter for both SogoUsersSources block is the filter as below;
"objectClass=mailUser AND accountStatus=active AND enabledService=mail AND enabledService=displayedInGlobalAddressBook";

my goal is only that every mail address can see global address book except for some accounts. For example there is a mail address called boss@domain.com.
i want boss@domain.com to become invisible from global address book. That's all.

I don't know how can i rearrange  the filter.

thank you.
