My first guess is that the global jenkins email configurations are not set correctly.

Manage Jenkins -> Configure System -> E-mail Notification

This is the default plugin, not the extended one you installed manually. The SMTP server field defaults to localhost, so unless you have an email server setup and running on the same box, this needs to be set.

If that is set then I would try telnet'ing to your email server from your Jenkins server to make sure there is not a connection error.
