I get a Pass when i run amavisd-new testkeys

However when i check the header of emails that are sent out i get a failed message. I've looked all over the net to try and find a fix but no joy so far.

This is the header of one of the email i sent to Gmail (From RoundCube)

Authentication-Results: mx.google.com;
       dkim=neutral (body hash did not verify) header.i=@vithusel.me header.s=dkim header.b=ztlvdFyd;

X-Amavis-Modified: Mail body modified (using disclaimer) -



I am currently sending adding signatures to emails using the disclaimer. Could this be causing DKIM to Fail?

No enough info for troubleshooting.
Any related error in Postfix log file?
