I recently moved my custom built social network from a shared server to a dedicated server. Since the move a lot more outgoing automatic email messages such as email confirmation, notifications, etc. seem to be ending up in the spam box or users saying they've simply not received them.
I need someone to ensure that this doesn't happen in the future and the chances of these emails ending up in spam boxes is minimised from here on. I've double checked and our mail server isn't blacklisted. This project shouldn't take more than a couple of hours for someone who knows what they're doing.
