All mail from my new Zimbra mail server is going into spam and junk folder of Yahoo or Hotmail. Any suggestion to deliver them direct into inbox?

Below is the header part of my mail from yahoo...

X-Spam-Flag: NO
X-Spam-Score: -1.963
X-Spam-Level: X-Spam-Status: No, score=-1.963 tagged_above=-10 required=6.6 tests=[AWL=-0.083, BAYES_00=-2.599, RCVD_IN_SORBS_WEB=0.619, RDNS_NONE=0.1] autolearn=no

Please use the Code Sample tag (CTRL-k) when pasting your mail header. It's impossible to tell where your line breaks are. – Scott Lundberg Mar 19 '10 at 13:45

I don't see any public IP addresses in your header... Did you send one to yourself? If so, that won't work. We need to see the headers after it arrives at Yahoo or Hotmail.
One thing I do see is that your mail server thinks you are on a SORBS Blacklist. If you are, then Yahoo and Hotmail will most certainly tag your emails as spam...

Update: You are on 5 blacklists according to: MXTOOLBOX. This is for sure the reason you are getting put in the junk folder at Yahoo and Hotmail.

[] was not found in the SORBS database – sahil Mar 20 '10 at 6:35
For some reason in the code above, SpamAssassin is showing RCVD_IN_SORBS_WEB, which is adding .619 to your score. Were you able to get headers from messages after they arrive at Yahoo? – Scott Lundberg Mar 20 '10 at 13:05
