You need to set up SASL authentication in the Postfix SMTP client (you 
have no idea how long it took me as a non-mail person to discover these 
buzzwords a few years ago :).

See http://www.postfix.org/SASL_README.html#client_sasl for some pretty 
good instructions.

Note that you might have to install additional packages to actually get 
it working. On Debian/Ubuntu, you need libsasl2, as well as 
libsasl2-modules, which has the actual authentication modules.

I can't give you specific configuration lines that are guaranteed to 
work with Yahoo, since I just started using pobox.com for relaying when 
Rogers made this annoying change.
