Hi Benoit, thanks for the reply.

My mailetconfig.xml now looks like this:

<processor state="local-address-error" enableJmx="true">
             <mailet match="All" class="MetricsMailet">

<folder>./bounces/</folder> </mailet>*
         </processor>

         <processor state="rrt-error" enableJmx="false">
             <mailet match="All" class="ToRepository">
                 <repositoryPath>file://var/mail/rrt-error/</repositoryPath>
                 <passThrough>true</passThrough>
             </mailet>
             <mailet match="IsSenderInRRTLoop" class="Null"/>
             <mailet match="All" class="Bounce"/>


* <mailet match="All"
class="com.internationalpresence.mailet.RecordBounceMailet">
<folder>./bounces/</folder> </mailet>*
         </processor>

however my mailet (RecordBounceMailet) still doesn't appear to be being
called anywhere when I trigger a bounced email.

Please can you point me to where I've gone wrong?

Thanks
Matt

Hello Matt,

1. is easy: just put it at the beginning of the transport protocol.

2. is slightly more challenging:
   a. For RemoteDelivery use onSuccess property to pass a callback upon
success (need another processor)
   b. For LocalDelivery pass property consume to false and handle success
afterward il a processor called "local-delivery" is a common practice.

3. is slightly harder. You would need to plug your logic in the various
places handling all kind of error: error processor, rrt-error processor,
bounces processor, local-address-error, relay-denied ...

Hope this helps.

Best regards,

Benoit

Hi there

I am hoping to implement three custom mailets for our James 3.8.0
installation:

1) to be called when an email is submitted via SMTP
2) to be called when an email is successfully delivered
OR
3) to be called when an email permanently fails to deliver

I was hoping to be able to tie the submission and success / failures
together based on message ID.

Is this possible and if so, can someone advise where best to place the
mailet tags? I've tried this (in mailetcontainer.xml) but it doesn't seem
to be getting called although I can see it gets initiated on startup:

          <processor state="bounces" enableJmx="true">
              <mailet match="All" class="MetricsMailet">
                  <metricName>bounces</metricName>
              </mailet>
              <mailet match="All" class="DSNBounce">
                  <passThrough>false</passThrough>
              </mailet>
<mailet match="All"
class="com.internationalpresence.mailet.RecordBounceMailet">
      <folder>./bounces/</folder>
</mailet>
          </processor>

Thanks and kind regards
Matt
