Frank, Are you using any 3rd party software for blocking emails? Did you enable RBL?

There is one domain that anyone in our company cannot receive email from. Is there somewhere in Exchange that lists blacklisted domains. If so how do I find it, if not what would cause us to get mail from all other domains except this particular one. I can get email directly from this domain if I use my home email account. Thanks frank
