The DNS RRs for mirc.com apparently contain a syntax error for the domainkeys:

"Authentication-Results: mta122.sbc.mail.re2.yahoo.com
from=mirc.com; domainkeys=fail (bad syntax)"

As domainkeys are one of the best ways to prove that e-mail originated from the sender claimed in the message header, many of us use success and failure of domainkeys validation as a discriminatory for spam.

Would you please consider correcting the domainkeys entry?

Thanks in advance,

Richard
