DKIM_STAT dkim_set_signer(
	DKIM *dkim,
        const unsigned char *signer);
);

| Called When | dkim_set_signer() can be called at any time prior to signature
generation. |  | 
|---|
| ARGUMENTS | 
    | Argument | Description | 
|---|
 | dkim | Message-specific signing handle, returned by
        dkim_sign(). |  | signer | A pointer to a null-terminated string which specifies the
	entity which is responsible for the signature being
	generated.  This will cause an "i=" tag containing this value
	to be included in the signature generated by this handle.
	If not defined, no "i=" tag will be added, meaning verifiers
	should use an implied value. |  | 
|---|
| RETURN VALUES | 
DKIM_STAT_OK -- success
DKIM_STAT_INVALID -- dkim referred to a verifying header rather
    than a signing header
DKIM_STAT_NORESOURCE -- out of memory
