I do not know that, but it seems in the same category, and possibly
worse than, those who send an email encrypted to those whose public keys
they know, and unencrypted to the rest of some mailing list.
Or even if the sender does not make that mistake, one receiver could
decrypt it and send it to others unencrypted.
It seems to me you must really trust the person to whom you send
encrypted e-mail, and to trust their computer systems as well. I could
imagine myself being paranoid enough never to send encrypted stuff to
people whose machines run Microsoft Windows, for example. As if I knew
anyone who gave a hoot about security and encryption anyway. 8-(
