Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

You can export your signing keys to a text file on the appliance. When you export keys, all of the keys 
currently existing on the appliance are put into a text file. For more information about exporting keys, 
see 

.

You can import keys that have been exported as well.

Importing keys causes all of the current keys on the appliance to be replaced.

Once you have associated a signing key with a domain profile, you can create DNS text record which 
contains your public key. You do this via the Generate link in the DNS Text Record column in the domain 
profile listing (or via 

domainkeysconfig -> profiles -> dnstxt

 in the CLI):

For more information about generating a DNS Text Record, see 

You can also view the public key via the View link on the Signing Keys page:

A domain profile associates a sender domain with a signing key, along with some other information 
needed for signing. 

A name for the domain profile.

A domain name (the domain to be included in the “d=” header).

A selector (a selector is used to form the query for the public key. In the DNS query type, this value 
is prepended to the “_domainkey.” namespace of the sending domain).
