Currently using iis 5.0 to work as a relay server from the internet into my exchange server on the inside of my network. Every now and then an email comes in that will stop every other email from being relayed. I find that if I remove the “Content-Type” line, then it will be sent just fine and all the other emails will start processing again. The following are some examples of the content-type lines that I have removed that fixed my problem.

My question is, “How do I prevent this problem from occuring so I don’t have to keep modifying these problem emails without changing my infrastructure?”
