In our company we have a mail server(proxy), but the problem is that we are recieving emails from outside where our email is not shown in the TO or CC!!,and the amazing thing is that this email is sent to many employees and the one who is sending the mails dont have any email adrress of any employee,
if you look down in the To: sberth@free.fr,this email is not even an employee email,so how our employees are  recieving an email not even sent to his mail address  nad not even CC'd!!!!??

Most mail servers have a way to block mails. For example, you can often block based on:

source IP
Sender address
Keywords in subject or body
pass/fail spam tests or authenticity tests

Check the documentation for the product you are using for how to do this.

You need to say what products you are using before anyone can tell you how to block email.

As a general point, presuming this is spam, blocking individual senders or ip numbers is rarely much use as the spammers vary such such things. You need to deal with the spam problem as a whole. Many ISPs offer server-side spam filtering, which is another possibility.

Blocking those types of messages isn't straight forward without blocking legitimate email. As already stated, it will be in the BCC field. You cannot rely on the To, From, or CC line to be accurate, because the BCC fields are hidden.

An antispam product should be blocking messages that look like spam, but the message that you have posted I would doubt would get blocked by any antispam applications.

Blocking email unless your domain is listed in the To or the From will basically mean that your users will not receive any newsletters or other bulk email (not always spam) from external receipts. If spam was that easy to deal with then it wouldn't be the problem it is.
