Cisco Cisco Email Security Appliance C170 User Guide

Make sure that you enter a valid domain name, for example, 

example.com

 is the domain 

name in the following email address: 

user@example.com

. If you have multiple domains 

in your organization, make sure that you add all the domains. 

If your organization is not using 

postmaster@domain.com

 or your administrator does not have 

access to the postmaster mailbox, create a message filter (on all your appliances) to redirect 
messages from 

SubmissionPortal@cisco.com

 sent to 

postmaster@domain.com

 to a different 

email address. The following is a sample message filter:

redirect_postmaster: if (rcpt-to == "postmaster@domain.com") AND (mail-from == 

"^SubmissionPortal@cisco.com$") { alt-rcpt-to ("admin@domain.com"); } 

For more information, see
