A friend tells me that some mail I sent to him at xtra.co.nz (now a
Yahoo subsidiary) was flagged as spam. He sent me the headers, but all
it shows is:
X-Apparently-To: [EMAIL PROTECTED] via hhh.hhh.hhh.hhh;
Thu, 21 Feb 2008 15:46:00 -0800
X-YahooFilteredBulk: 77.75.108.10
X-Originating-IP: [77.75.108.10] Authentication-Results:
mta105.tnz.mail.aue.yahoo.com
from=gregorie.org; domainkeys=neutral (no sig)
I wrapped the lines to suit the e-mail. These are the only indications
of why my mail was treated as spam. What is this domainkeys of which
they speak?
Can anybody point me at an explanation? Words or a URL would be equally
good.
Thanks,
Martin
