Hi Jessica,
ePADD Discovery, designed to be mounted on a publicly accessible web server, does not currently support providing access to non-redacted messages/attachments.
However, ePADD Delivery, designed to be accessed from a secured workstation in a repository's reading room (or the equivalent), supports providing full access to all (non-restricted) messages, including attachments.
We have discussed the possibility of enabling users to mount ePADD Delivery to a public web server, in cases where all of the mail and attachments can be accessed without restriction. But we have not implemented this -- please let us know if this is a direction you would like to pursue. As our current grant support ended in February, we are currently unable to pursue this development work on our own.
Best,
Josh
