I believe you have at least two problems:

1. I am guessing that php.ini-recommended and php.ini-dist are respectively an example and a template configuration files; modifications to them may not impact the "real" php.ini, currently used by your instance of PHP. Use phpinfo() to make sure that your configuration is correct.
2. Spam filters. Jeff Atwood has a pretty good blog post about implementing the checks that servers do when checking if your email message is spammy. Don't forget:

Just because you send an email doesn't mean it will arrive.
