It is very common to have lower confidence in newly registered domains
since spammers register thousands of domains daily, send with them for
a few hours, and then purge them after a day or two. I know that used
to be common, I do not know if it still is.

Also make it something other than *.info, which on my system has never
sent a valid email, all have been marked as spam.

It's free and easy to do, I strongly encourage you to do so.

Do you know how DNS resolvers work?  Your TTL on your DKIM records are
86400, which is 24 hours.  The SOA for your domain is:
powersoftindia.info.    86400    IN    SOA    ns1.powersoftindia.info.
powersoft.powersoftindia.info. 2011012809 10800 900 604800 86400


That negative TTL of 86400 means that you're telling other DNS servers
to remember NXDOMAIN responses for 86400 seconds (24 hours). So if
you sent a test message to Yahoo before you had configured that TXT
record in your DNS servers, Yahoo tried to look it up, got a NXDOMAIN,
and then remembered it for 24 hours.

Since yahoo is reporting that the key doesn't exist in DNS (and it
obviously does in my dig tests), that's what I suspect is happening.
