Re: Setting up environment for developing Mailet

Hi Mark,

I'm surprised nobody gave you the link to the how-to customize mail 
processing in the official doc, but should greatly help I believe (which 
is based on the example linked by Benoit, but with a step-by-step 
guide): https://james.apache.org/howTo/mail-processing.html

Also to know if your mailet was loaded correctly or not... did you add 
it in the mailet processing (aka mailetcontainer.xml file)? If you try 
to add your custom mailet in your pipeline, if James didn't load it and 
then find it, it would just throw at startup. If you added it in the 
pipeline and your server starts, it's likely that it loaded successfully 
I believe.

Rene.
