Hi,

I removed the g= bit and added v=DKIM1 from my DNS.  The old error went
away, but when I send an email to autoresponder
at [EMAIL PROTECTED] I now get a new failure message:

Result:                   DKIM signature NOT confirmed
Description:              Signature verification failed; signature
is missing or key could not be found

Authentication-Results:
sendmail.net [EMAIL PROTECTED]<[EMAIL PROTECTED]>;
sender-id=neutral;
spf=neutral

Below is the dkim.conf (configuration file) that I am runing against
"dkim-filter -x dkim.conf":

Canonicalization relaxed/relaxed
Mode s
X-Header True
SubDomains True
Domain prog.devbms.com
#ExternalIgnoreList ftp.example.com
KeyFile /etc/mail/brandmail/keys/prog.devbms.com.priv.pem
Selector 9999
SignatureAlgorithm rsa-sha1
Socket inet:[EMAIL PROTECTED]
Syslog Yes
Userid mailnull

Thanks.
