From DKIM.ORG:

DKIM enables a mechanism that permits potential email signers to publish information about their email signing practices; this will permit email receivers to make additional assessments about messages. DKIM's authentication of email identity can assist in the global control of "spam" and "phishing".

Its one of the possibilities that Yahoo! might marked the email as spam because the message is not signed with DKIM signature when is sent "DKIM defines a domain-level digital signature authentication framework for email".

There are also another headers that Yahoo! might mark them as spam.
