I recently migrated a Rails app I had on Heroku to my domain Hosted on Dream Host and it caused issues with my Google Apps mail. I asked Dream Host and their solution didn't seem to work, and when I asked it here I got down-voted, so I was wondering where I could/should ask that. I want to make sure I use this site properly.
