* These features can send messages to special queues called Quarantines.

LDAP validation for recipient acceptance occurs within the work queue. If the 
recipient is not found in the LDAP directory, the message is dropped or 
bounced. LDAP validation can be configured to occur within the SMTP 
conversation instead.

Masquerading occurs in the work queue; it rewrites the Envelope Sender, To:, 
From:, and/or CC: headers, from a static table or via an LDAP query.

LDAP queries are performed for message routing or address rewriting. Group 
LDAP queries work in conjunction with message filter rules 

mail-from-group

 and 

rcpt-to-group

Message Filters are applied prior to message “splintering.” * Can send 
messages to quarantines.
