We host our own website and email internally with W2k8 IIS and Exchange 2k7. We just deployed a website a week or so ago, and part of the website is a web application that sends confirmation emails and such.
Some people are reporting that emails from our domain go to their spam folder. Is there anything I can do about this besides educate them on checking the spam folder? We dont do any bulk mailing, everything we send is a reply from an online purchase.
