Hello.
Please, help me resolve the problem. We use Exchange Server for mail.
Any user using, for example, Thunderbird, can substitute the address of the sender. A user of my organization can receive a letter (mail) from any invented mailing address. The real address of the sender can be viewedonly in the details of the message.
How to configure the Exchange Server so that the user in the column "from:" was displayedthe
real address of the sender?
Thank you.
