You might want to run this plugin analyzer to see if a certain plugin is eating up your memory for your site and consider disabling the heavy ones. Feel free to stop by live chat at dreamhost.com for instant support. Also, check what php version you are running for wordpress. Try 5.3 fast cgi or 5.4 fast cgi php for wordpress sites.

You are correct, Dreamhost does have spam preventative measures that require your email script From headers to be either a dreamhost hosted email account or use smtp authentication to send your messages, as described below:

You could try to install & configure this WordPress plugin to use these
SMTP authentication settings:
http://wordpress.org/extend/plugins/configure-smtp/
If you install and use this plugin, this should correct all the
webforms/plugins on this site to use the settings you configured. Also make sure your wordpress username is tied to a dreamhost hosted email account.

Sample Plugin SMTP authenticated settings:
smtp server: smtp.gmail.com
ssl is on
smtp authentication is on
port 465
user: your.email@gmail.com
pass: your password

I fixed up your site for you, you had the wrong wordpress database user and password listed in your wp-config.php file. Feel free to send issues to support@dreamhost.com anytime. Have a good day 🙂
