<looking at the code and the ant 1.7.0 jars files>
The ant-email.jar file does not contain the mail task. <mail> is
not an "optional" task. and is located in ant.jar, however if mime
types are used, the EmailTask code will attempt to load MimeMailer
(which is in ant-email.jar) by doing the following:
         mailer = (Mailer) ClasspathUtils.newInstance(
                       "org.apache.tools.ant.taskdefs.email.MimeMailer",
                            EmailTask.class.getClassLoader(), Mailer.class);

Which seems a bit pointless from a deployment point of view, but it
does allow the EmailTask to get compiled without depending on
javamail.jar in the classpath.

This means that the moving ant-email.jar from $ANT_HOME/lib will
not work.

The EmailTask code could be modified to allow a classpath element to be used
to load the MimeMailer class (with junittask like classloader tricks),
but in the meantime,
one  can use the cl:classloader task.
