116  Quarantine GFI MailSecurity for Exchange/SMTP
Active Directory or email server, GFI MailSecurity will delete the
blocked email instead of storing it in the quarantine store.
The Directory Harvesting filter determines if a user exists or is local,
by performing user lookups against the Active Directory or LDAP
server you configure.
To enable the Directory Harvesting filter on the quarantine store,
follow these steps:
1. Click the GFI MailSecurity  Quarantine Options node.
2. Click the Directory Harvesting tab.

Active Directory lookups and skip to step 7. If you want, you can
choose to use LDAP lookups, as outlined in the next step.
5. If you installed GFI MailSecurity in SMTP mode, click Use LDAP
lookups.
6. Specify the LDAP server name or IP in the Server box and the port
number, default 389, in the Port box. If your LDAP server requires
authentication, ensure that the Anonymous bind check box is clear
and enter the authentication details in the User and Password boxes.
