I just noticed this today when I accidently left my Eudora settings set to one provider's SMTP server even though I was connected to another provider. I was still able to send e-mail. It ocurred to me that since passwords are required to read mail, but not send mail, that it must be possible to use just about anybody's mail server to send mail. Is this a commonly accepted practice in the Internet community? Doug Lerner, Tokyo
