How have you identified that they are actually being delivered by your 
server itself?

It is my experience that this is likely not the case, and it is only 
your addresses that are being forged.

The only way to tell for certain is to review the headers of the message.

If you wish, send the email headers (privately if you want), and we can 
identify whether or not it is in fact your server delivering these messages.
