I have configured Zimbra-4.0.4 on CentOS-4.4 and i am using external LDAP for authentication. Thing are working fine for me . And i have configured the IM functionality of Zimbra using zmprov ma firstname.lastname@example.org ZimbraFeatureImEnabled TRUE. So my users can chat through Zimbra. But the problem is users won't get messages unless they press refresh button for each each messages. Can anyone pls tell how to overcome this problem.
Thanks in advance
