opendkim.chunk_end()

DESCRIPTION

This call terminates one or many calls to opendkim.chunk(), and will return the DKIM results the same way opendkim.eom() does. When using opendkim.chunk(), one must validate the message using this call.

opendkim.chunk_end() is called to validate a message when done calling opendkim.chunk().

ARGUMENTS

Type: undefined

RETURN VALUES

• On failure, an exception is thrown that indicates the cause of the problem.

NOTES

• All the same notes for opendkim.eom() apply here.
