We are, as many of you are also, experiencing an increasing number of forged from adresses in email sent to our domains. Traditionally we have allowed external mail to claim to be internal senders for a number of reasons. What I would like to do is only permit hosts within our address space to claim to be user@ourdomain(s).com and deny all external hosts claiming to be user@ourdomain(s).com (with an appropriate error message). How do I do this? I am not asking for you do to my homework, just point me where I can find what I need if you could be so kind.
