I'm using a basic Ubuntu Server 9.10 x64 installation with Postfix/Amavis/DKIM
setup. My outgoing mail is signed fine. However, the incoming mail doesn't
appear to be.
99.9% of the mail comes in with this in the mail log:
<code>
dkim-filter[1626]: 07CF5134C5: no signature data
</code>
I did have one come in with this in the log:
<code>
dkim-filter[1626]: CD2CCD95 ADSP query: syntax error in policy data
dkim-filter[1626]: CD2CCD95: no signature data
</code>
and another one with this one (and this is the one that makes me wonder about
DNS resolution):
<code>
dkim-filter[1626]: 7E6FDD95 ADSP query: timeout DNS query for `d49.org'
dkim-filter[1626]: 7E6FDD95: no signature data
</code>
This error comes from the header of an email from gmail user:
<code>
domainkeys=softfail (invalid, public key: DNS query timeout for
gamma._domainkey.gmail.com)
</code>
Do most senders *NOT* use DK or DKIM signatures? Do I have a problem with my
DNS? How can I troubleshoot/fix?
Thanks for your help.
Sincerely,
Ernie Grossmann
