  <pre wrap="">Hi Wael!

How's the 1.2 release going :-)

I was wondering about a spring integration for greenmail, s.th. like

    &lt;!--
        Test mail server.
    --&gt;
    &lt;bean id="greenMailBean" class="com.consol.cmas.esb.test.GreenMailBean"&gt;
        &lt;property name="autostart" value="true"/&gt;
        &lt;property name="smtpProtocoll" value="true"/&gt;
        &lt;property name="pop3Protocoll" value="true"/&gt;
        &lt;property name="users"&gt;
            &lt;list&gt;
                &lt;value&gt;to:password@localhost&lt;/value&gt;
                &lt;value&gt;from:password@localhost&lt;/value&gt;
            &lt;/list&gt;
        &lt;/property&gt;
    &lt;/bean&gt;

I attached the GreenMailBean.
Would you rather leave this out/add it to eg 'contribution' or
'integration' subproject?
Maybe this would be a nice extension for the spring-modules project.

Cheers,
Marcel
