Hello Mat,
what is the status with this package. We will start tomorrow (tuesday, 17th of June) with the extension of acs-mail-lite to support the bouncemanagement most likely using VERPs. Anything that you have developed would be cool to lay hands on so we could save some work.
For the rest of the commmunity, we will develop a bouncemanagement system for acs-mail-lite within the next 7-10 days, we already enabled immediate sending of emails (without storing them in the database for the scheduler).
