dkim=fail for inbound mails

I observed most inbound mails are marked with dkim=fail

Code: Select all

Authentication-Results: mail.domain.com (amavisd-new);
	dkim=fail (2048-bit key) reason="fail (body has been altered)"
	header.d=gmail.com
and scored like this:

Code: Select all

DKIM_SIGNED=0.1, T_DKIM_INVALID=0.01
What should I check?

code: mail.NO_SUCH_PART error when replying/forwarding a message

Usually this happens when the received mail has images, and user has not yet clicked 'display images'. When user replies or forwards the mail, the image part was not loaded and therefore this message occurs.
