Submit and commit your changes.

If you enable envelope sender verification or disable allowing partial domains in SMTP Address Parsing 
options for a listener, the default domain settings for that listener will no longer be used.

These features are mutually exclusive.

Accept Queries

For Accept queries, select the query to use from the list. You can specify 
whether the LDAP Accept occurs during the work queue processing or 
during the SMTP conversation.

For LDAP Accept during the work queue processing, specify the behavior 
for non-matching recipients: bounce or drop.

For LDAP Accept during the SMTP conversation, specify how to handle 
mail if the LDAP server is unreachable. You can elect to allow messages or 
drop the connection with a code and custom response. Finally, select 
whether or not to drop connections if the Directory Harvest Attack 
Prevention (DHAP) threshold is reached during an SMTP conversation.

Performing recipient validation in the SMTP conversation can potentially 
reduce the latency between multiple LDAP queries. Therefore, you might 
notice an increased load on your directory server when you enable 
conversational LDAP Accept.
