That's a DomainKeys policy record. The DKIM spec doesn't support
DomainKeys policy, and neither does the dkim-milter.

Aside from the spaces in the key (which would certainly break it), all
of these are incorrect by virtue of being at _domainkey.<domain>. Each
key must have a selector name attached, and that selector should be the
first part of the DNS label. For example, I'm currently using the
selector "mail", so my DKIM key is in DNS as such:

mail._domainkey.markley.org IN TXT "v=DKIM1\; k=rsa\; t=y\;
p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDY8qM22+BZVHexjzQUufK/E1TIZbJgRt98MeMiK8CI0W01mJ/C71Ysh2EyK8CHw2wWKqij9ewHIj/Oj/+diW0SIc0B4rfBPw1rAYaXvqX725/NSVVbKOhjujLk4cDec5NclR0D8t0dwwrk9rbfIIjPrlpfXGPgTbfaDP0tvR9XPwIDAQAB"

Regarding your other questions for the list: The first issue looks like
an OpenSSL error, possibly caused by a broken key being published; you
should check and see if the messages causing those errors are coming
from a consistent sending domain or small set of sending domains. Also,
2.7.0 is the current stable release of dkim-milter. There was a beta
release of it previously available, which may be the source of your
confusion. I believe that was labelled as such in the version number.
