The problem is that I sent a message to a person who added
some text in my message and then forwarded it on to a
third person, who now thinks I wrote all that stuff and is
really pissed off. How can I prove that it wasn't me who
wrote it? And I don't have the mail in my sent
item/deleted item anymore.
If the person doesn't believe you when you tell them, you have an
interpersonal problem, not a mail problem. There is no way to "prove" you
didn't write what was in the forwarded message. This is a good case for
digitally-signed messages. Get a program like GnuPG and digitally sign your
messages. Give your public key to those people for whom you'd like to prove
messages contain your words only. If they receive a message from a third
party claiming to contain your words, the digital signature will prove
whether or not the message came from you, since it's based on the content of
the message as well as the sender. If anyone were to add or subtract
information from the message, it would be detectable on the receiving end.
