Where do you find this requirement? Blindly creating sender fields based on this assumption violates RFC2822. If present, the sender field must contain a single mailbox. "login @ fqdn" does not qualify in many cases, and there is nothing requiring it should (even if there were: Would it justify violating RFC2822?) If the originator of the message can be indicated by a single mailbox and the author and transmitter are identical, the "Sender:" field SHOULD NOT be used. I do see that this text can be interpreted in different ways, but let's interpret it in a way that makes sense. When are the author and transmitter identical? Most of us write mail wearing different hats and using different machines to transmit it, maybe even different logins on the same machine. But the important difference is always which hat we are wearing. In my opionion, the author and transmitter are always identical when they represent the same person. If I write a message with the bmork@dod.no hat on, then that's the hat I am using when transmitting it too. Where I am transmitting it from doesn't change this. With this interpretation, including a sender field would be illegal in all cases where a single author transmits his own mail. A sender field should only be added when transmitting mail on behalf of others, or when the mail has multiple authors. Bjørn
