We are facing a rather weird issue.
We are running SBS2008 with exchange.
Everyting runs smoothly, except one thing. When a specific gmail account sends an email, if the email is plain text is proccessed properly, if the email is with attachement it is not delivered. When that guy sends that email to mine and i forward it to the original recipient it is delivered properly. It looks like there is an issue only with the specific sender (gmail) / receipient (exchange account).
