Cisco Cisco Email Security Appliance C190 Guia Do Utilizador

Note that there is a potential complication with LDAPACCEPT and Lotus Notes. 
If Notes LDAP contains a person with attributes like these:

Lotus accepts email for this person for various different forms of email addresses, 
other than what is specified, such as “Joe_User@example.com” — which do not 
exist in the LDAP directory. So AsyncOS may not be able to find all of the valid 
user email addresses for that user.

One possible solution is to try to publish the other forms of addresses. Please 
contact your Lotus Notes administrator for more details.

AsyncOS supports alias expansion (LDAP routing with multiple target 
addresses). AsyncOS replaces the original email message with a new, separate 
message for each alias target (for example, recipient@yoursite.com might be 
replaced with new separate messages to newrecipient1@hotmail.com and 
recipient2@internal.yourcompany.com, etc.). Routing queries are sometimes 
known as aliasing queries on other mail processing systems.
