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).

A canonicalization method (the method by which the headers and content are prepared for 
presentation to the signing algorithm). AsyncOS supports both “simple” and “nofws” for 
DomainKeys and “relaxed” and “simple” for DKIM.

A signing key (see 

 for more information).

A list of headers and the body length to sign (DKIM only).

A list of tags you want to include in the signature’s header (DKIM only). These tags store the 
following information:

The identity of the user or agent (e.g., a mailing list manager) on whose behalf the message is 
signed.

A comma-separated list of query methods used to retrieve the public key.

The timestamp of when the signature was created.

The expiration time of the signature, in seconds.

A vertical bar-separated (i.e., 

|

) list of header fields present when the message was signed.

The tags you want to include in the signature (DKIM only).

A list of Profile Users (addresses allowed to use the domain profile for signing).

The domain in the addresses specified in the profile users must match the domain specified in the 
Domain field.

You can search through all of your existing domain profiles for a specific term. See 

 for more information.

You can also choose whether to sign system-generated messages with DKIM signatures. See 

 for more information.
