Hi all, I'm having a small problem in one of my client's office as they usually send e-mails to their customers with CC for multiple addresses, but lately they have been receiving an untomated response telling them they don't have the right permissions to send e-mails to those addresses. I haven't set up any rules in the outgoing nor incoming protocols, but I have the doubt if that response comes from the inner MS Exchange 2K or their clients one.
