Hi Charles,

Here's the signature from one of your messages:

DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/simple; d=yahoo-inc.com;
        s=cobra; t=1323798669;
        bh=52ie9MK1spY/nKiwEUuZa/1PX2boh4O50cZEr4upubU=;
        h=Subject:Mime-Version:Content-Type:From:In-Reply-To:Date:Cc:
         Message-Id:References:To;
        b=Y2zjPTxlyf4/4hoKCfUqPGLin29nrTyPouIqxSMb6F4papH3DeAHB9VpBsmor1PQe
         Kb58Trp7OKUmnsklYQ52cflDZ++HfClRj8D73rTMpTRiFNlGOzGKOGqLRcqq0kp+QD
         su7h8+9A/QznUKbLdZBJqS6/C9di297L3kNxp9tc=

and here's the signature from your test message:

DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/simple; d=cctw.yahoo-inc.com;
   s=care; t=1323797667;
   bh=fdkeB/A0FkbVP2k4J4pNPoeWH6vqBm9+b0C3OY87Cw8=;
   h=To:From:Subject:Date:Message-ID; z=To:=2

The error at the verifier's end is "syntax error: missing
parameter(s) in signature data". The "b=" tag is missing. Can you
send me a test message from that host?

Regards,
