Hello, we are running exchange 2007 on Win Server 2003 and using greylisting for spam control. There's been occasion where someone's email ends up in the junk folder. These emails are all send internally. How do I make sure that all internal emails are white listed? Or any idea on what can make an email go to the junk folder randomly? In most cases, the email is sent to mutliple internal users and they all recieve the email in their junk folder. Do you need more information to help me? Thanks.
