Can I authenticate to the SMTP server on the 'from' address only?
No - authentication on the 'from' address only would be very insecure as anyone could easily 'spoof' your email address and send mail through your account.
AuthSMTP authenticates using a username and password and also on the 'from' address - this provides a much higher level of security.
