I have a Zimbra user who's "Emailed Contacts" is not being updated. His "Add new contact to Emailed Contacts" preference is enabled. And his LDAP settings I think are correct:

zimbraFeatureContactsEnabled: TRUE
zimbraFeatureContactsUpsellEnabled: FALSE

Were running:
Release 6.0.10_GA_2692.RHEL5_64_20101215161355 RHEL5_64 NETWORK edition

Any ideas why this is happens, and how can I fix it?

Thanks for you assistance!
