>I have an application that has a way to email quotes in the form of a PDF attachment. I use smtp via exchange server in my office to send the emails. I am having problems with the email getting filtered out by spam filters at certain customers location. My users can send the same email through their Outlook client without problems. Is there something I can do to my emails fix this problem or am I going to have to change to MAPI?

You must ask your customers to change their spam filter criteria.
