Also watch what you say in your subject. We simply say "Order Confirmation #".
Also, next to the e-mail field in your order placement form say "Please try to avoid free e-mail addresses (ie. hotmail)"
I can relate to your problem/worries. For one of my clients we added a "NOTICE" in big red text on the confirmation page that says they will be receiving a confirmation email(and other emails) from the company and the from email address would be "orders@companyname.com"...kind of giving them a heads up. We added some text to explain that sometimes the emails can be incorrectly sent to a "Junk" or "Spam" folder. If they don't receive the confirmation email within X hours to make sure they check these folders for the email. etc. etc.
