The error message is generated by's SMTP server. This is an anti-spam technique at work. In order to use Yahoo's SMTP server, you must *first* use POP3 to check your mail. The POP3 server notes your IP address and allows that address to access the SMTP server for sending. (The theory is that if you prove you've got a valid username and password on their mail box, you're okay to send through it.) The solution is to open a POP3 connection prior to attempting to send mail. The connection can be immediately closed, it just wants your username and password for verification. temppop: open pop://user:[pass--mail--yahoo--com] close temppop send [postmaster--yahoo--com] "This works from Yahoo."
