DomainKeys Identified Mail (DKIM) milter in Python
The dkimpy-milter is a Sendmail/Postfix Milter application that signs
and verifies DKIM (DomainKeys Identified Mail). It supports both traditional
RSA (RFC 6376) signatures and the new ed25519 based signatures defined in
RFC 8463.
.
DKIM provides a way for senders to confirm their identity when sending email
by adding a cryptographic signature to the headers of the message.
.
It uses the OpenDKIM configuration option naming and definitions, for the
options it implements, to make it easy for OpenDKIM users to experiment with
this alternative.
