The canonicalization algorithm to use when signing 
by DK. Currently supported algorithms are 

simple

 

and 

nofws

. Default is 

nofws

.

The body canonicalization algorithm of to use when 
signing by DKIM.  Currently supported algorithms 
are 

simple

 and 

relaxed

. Default is 

simple

.

The headers canonicalization algorithm of to use 
when signing by DKIM.  Currently supported 
algorithms are 

simple

 and 

relaxed

. Default is 

simple

.

Number of bytes of canonicalized body that are used 
to calculate the signature.  Is used only in DKIM 
profiles.  If used this value becomes 

l

 tag of the 

signature.  By default it is not used.

Detrmines how to select headers for signing.  Is used 
only in DKIM profiles.  Can be one of 

all

, 

standard

, 

standard_and_custom

. 

all

 means to sign 

all non-repetitive headers.  "standard" means to sign 
pedefined set of well known headers such as Subject, 
From, To, Sender, MIME heades etc. 

standard_and_custom

 means to sign well known 

headers and user-defined set of headers. Default is 

standard

.

User-defined set of headers to sign. Is used only in 
DKIM profiles if 

headers_select

 is 

standard_and_custom

.  Default is empty set.

Determines whether to include the 

i

 tag into the 

signature. Possible values are 

yes

 or 

no

. Default is 

yes

.

The identity of the user or agent on behalf of which 
this message is signed. The syntax is a standard 
email address where the local-part may be omitted.  
Domain part of this address should be a sub-domain 
of or equal to the 

<domain>

. This option is only 

applicable if 

--i_tag

 value is set to 

yes

. Default is 

an empty local-part followed by an 

@

 and by the 

<domain>

.

Determines whether to include the 

q

 tag into the 

signature. Possible values are 

yes

 or 

no

. Default is 

yes

.

Determines whether to include the

 t

 tag into the 

signature. Possible values are 

yes

 or 

no

. Default is 

yes

.

Determines whether to include the 

x

 tag into the 

signature. Possible values are 

yes

 or 

no

. Default is 

yes

.
