Explain how Schleuder finds the key to use if resend* is invoked
People had the wrong assumption, that they need to use x-set-fingerprint
in a case, in which someone, who is not a subscriber of a list, but gets mail send via resend*
, changed their key.
I guess it would help if the docs would shortly explain how a key lookup in such a case works, and, especially, that Schleuder fails to handle resend*
if there is more than one matching key found.
