I was sending a list of reports yesterday to various companies. All of the companies are in my address book, a copy is sent to the company and a copy bcc'd to me. Somehow one of the reports was sent to another company in my address book even though the "To" field states it was sent to the correct company. The mail was returned by the incorrect company and in the return email there was no mention of that company in any of the "To" or "CC" fields.
How could this email have been sent to them without them being in the recipients list and with no mention of them at all in the email.
Any help would be greatly appreciated.
