Not exactly what I want. I want a free form From: field where I can make up
identities on the fly, for my own domain for example. I don't want to create
identities for some addresses that I maybe use only once (e.g. to sign up for
an announce mailing list I would use something like this someid-product-
<email address hidden> and then never need to use this identity as I could
never post to this list).
