    Hello -

    I cannot get the DKIM feature of the SBG 9.0.1-10 to work correctly. I keep getting signature not found. Here are the headers from yahoo:

    Authentication-Results:   mta102.mail.ac4.yahoo.com from=exchangetest.com; domainkeys=neutral (no sig); from=exchangetest.com; dkim=permerror (no key)

    and from google.com

    Authentication-Results: mx.google.com; spf=pass (google.com: domain of prvs=884825a7c1=robert@exchangetest.com designates 64.81.85.242 as permitted sender) smtp.mail=prvs=884825a7c1=robert@exchangetest.com; dkim=neutral (bad format) header.i=user@exchangetest.com

    DKIM-Signature: v=1; a=rsa-sha256; d=exchangetest.com; s=august2010; c=relaxed/relaxed;
    q=dns/txt; i=user@exchangetest.com; t=1282319424; x=1284911424;
    h=From;
    bh=i7x9408S3zUmxu/GZdU3NUzqk1teJAIYIBP2RwgBnEw=;
    b=cijWXyfawca+KIKHYDkMI7lHV5VhC/uW1uh1KDa+KxPAYXmj6cofm0Qr3O5nvFMq
    fKgYjfrpTghETVarzk6iww==;
    X-AuditID: c0a801ca-b7c77ae0000038ca-04-4c6ea43f1a63

    Any ideas where i can go from here? I have tried and tried and keep getting bad signatures, i am not sure if this is a DNS record problem or if this is a simple configuartion problem.

    Thanks for your help
