@Abhishek: Ashish's is the most accurate response. There's no quick fix
for this - if you already have a Gmail account, then you are much better
of using Gmail's SMTP instead of your own, which you can configure in
Postfix. Of course, you cannot set an arbitrary address in there.
If you notice, there is a lot of change in the way mails are handled
these days. For instance, Gmail relies on SPF and DKIM (Domain Keys
Identified Mail), and still it can send your mail to Spam if your
reputation has not been good. Yahoo on the other hand requires Domain
Keys only (for which you've to use dk-filter/milter and not
dkim-filter), and may require participation in its Feedback Loop.
Hotmail requires you to have SPF & Sender ID configured, AND, to ensure
delivery you need to go through their JMRP (Junk Mail Reporting Program).
And, goes without saying, PTR, not listed in DNSBL, having a correct
'helo' name, and some criteria as mentioned in CAN-SPAM Act are to be
followed. You really have to spend some time doing this right, and you
have to ensure that you maintain your reputation all times.
All the best with your endeavor ;-)
