   Huh, antispam/antivir server add some records to the mail's header, like:
   Received: by (Postfix, from userid 8)
         id 5625628308; Wed, 9 Nov 2011 07:58:14 +0100 (CET)
X-Spam-Status: No, version=123456789
X-Spam-Checker-Version: Antispam
Received: from (localhost [])
         by vbms.DUMMY (Postfix) with SMTP id 2F711282A0
         for <>; Wed, 9 Nov 2011
07:58:14 +0100 (CET)
Received: from ( [])
         by (Postfix) with ESMTP id 0DC89282A0
         for <>; Wed, 9 Nov 2011

X-DKIM: Sendmail DKIM Filter v2.7.2 0DC89282A0

         (verification failed); dkim-adsp=fail
X-DomainKeys: Sendmail DomainKeys Filter v1.0.2 0DC89282A0
Authentication-Results:; domainkeys=fail (no

   Could be it ? So it is able to sign only body ? Or what do you recommend ?
   Thank you very much
