Yahoo failed as internet company for a reason. Try sending an email with a link to a bank website. E.g. CIMB (Popular across Asia)
http://www.cimb-bizchannel.com.my/index.php?ch=srvpack
Your email will be rejected by Yahoo. Just awesome…
Workaround: Use a shortlink to hide your URL. E.g. http://goo.gl/tPb19A. Now your phishing emails will arrive safely. 😉
