When he sents a mail to another user of that company it works: email@example.com to firstname.lastname@example.org. All of our company can sent email to email@example.com without an error. We use Exchange 2007. I think the problem is the other side. Is it possilbe to deny the receiving of emails from one sender to one recipient in Exchange?`
