dovecot - Sep 2015 - Sieve and forward

Hi
I have already posted to the postfix group, however, I believe that sieve
and dovecot should be able to fix this problem.
When I receive a message from yahoo and the user forward it to a gmail or
yahoo acount this email is considered as spam or
rejected.
>From yahoo is rejected since it seems that I am try to send spam since the
email should be signed with dkim.
Is there a way to encpuslated or sign in some way.

Thank you

Hi,

I think the problem is you cannot resign the forwarded message... and if
you keep the original sender domain it looses the signature? I'm not a
DKIM guru though :-) Maybe just forward it as attachment from the users
address...

regards
Marco
