I have a classified ads site that sends emails (for example activation mails). Some of the emails to Hotmail and Gmail accounts are now being marked as spam.
To resove this, I will change the PHP mail function that I use now, to PHPMailer.
However, we installed PHPMailer and did some tests, but most of emails to hotmail and GMail still end up in SPAM. This is a major problem, others coders already searched but couldn't find a solution.
You get your money if you succeed in setting up a PHPMailer setup on my server. In a period of 7 days I will test the setup by sending emails through Phpmailer to new Gmail and Hotmail accounts. If all e-mails do arrive in inbox, you win.
What should you do? Review RDNS, Nameservers, Domainkeys, SPF, Blacklists, etc, etc. If possible, get me on whitelists, just do whatever you need to get me going.
I will not give you acces to my server (Linux with DirectAdmin), just tell me what to do and what information you need.
**It is important that the site keeps functioning and sending mails at all times. It is a live project! **
