There is a very similar question here regarding using PHPMailer and Spam - https://stackoverflow.com/a/16717647/1676190

This does sound more like a configuration issue with your mail server and/or your DNS server. Your mail server does not appear to be "trusted" enough, so you don't get enough "positive" points from GMail (and mail clients). I notice that you're using postfix as your mailer... Have you configured it properly?

I would suggest you configure postfix first. For example, here's a guide on how to do it in CentOS:

http://wiki.centos.org/HowTos/postfix

Second, you should add an SPF record to your DNS server:

Third, it would be good to have a reverse lookup entry for your server:

You will need to do the above and some more to make sure that clients don't flag your mail as spam, and you don't get blacklisted

Here's a good list of things to do to avoid getting blacklisted:
