I have a very straight forward build.xml file:

<project name="test" default="test" basedir=".">
    <target name="test">
        <mail
            from="[EMAIL PROTECTED]"
            subject="Test Email"
            mailhost="192.168.128.100"
            user="dweintraub"
            password="xxxxxxxx"
            message="This is a test email"
            failonerror="true">
            <to name="David Weintraub"
                address="[EMAIL PROTECTED]"/>
        </mail>
    </target>
</project>

When I attempt to execute it, I get the following error message:

test:
     [mail] Failed to initialise MIME mail: javax/mail/MessagingException

BUILD SUCCESSFUL

--- Looking at the source code:
src/main/org/apache/tools/ant/taskdefs/email/EmailTask

Which is strange because I set "failonerror" to "true".

This is a bug.
The code does not check the failonerror flag here and simply returns.

[mail] Failed to initialise MIME mail: javax/mail/MessagingException

This is due to "helpful" code in EmailTask,  a buildexception is
thrown by classloader utilities -
"Class org.apache.tools.ant.taskdefs.email.MimeMailer could not be
loaded because of an invalid dependency." with a cause exception:
Caused by: java.lang.ClassNotFoundException: javax.mail.MessagingException
however EmailTask#logBuildException() only reports
the message in the cause by exception (javax.mail.MessagingException).

The root cause that can give this exception is a missing
javamail[anyversion].jar file.

you seem to be having problems getting the javamail.jar into
the right place (whatever ANT_HOME/lib that is used by
cruise control ?). Try at the command line.
(NOTE: for linux users, if you installed the jpackage version
of ant, the file /etc/ant.conf will override ANT_HOME for pre ant 1.7.0).

In the mean time, you can use the excellent classloader task
to add the javamail.jar to your project classloader:
from http://enitsys.sourceforge.net/ant-classloadertask/
  <typedef uri="antlib:net.jtools.classloadertask"
           resource="net/jtools/classloadertask/antlib.xml">
    <classpath>
      <fileset
        dir="${user.home}/tools/ant-classloader"
             includes="*.jar"/>
    </classpath>
  </typedef>


  <cl:classloader loader="project">
    <classpath>
      <fileset dir="${user.home}/tools/javamail/" includes="*.jar"/>
    </classpath>
  </cl:classloader>

  <mail ...>

Any ideas? I am currently sending mail via CruiseControl and that
works (and where I got the parameters from) so I know that it is
possible to send email from this machine.
