Automatic usage of all available command plugins

For me the confusion was probably my fault because part of my immediate need was to post emails to a node with text, image or text+image so I went in with the assumption that attachments would be parsed out of the box. Stepping through the Feeds importer (admin/structure/feeds) was the obvious place to look but if I didn't have some experience with Feeds I may not have thought to go there.

Since there are only three Command plugins I'd vote for the default being all active, though I can see how allowing users to mail comments and wanting to control attachments could be a common case and I don't know what would happen if the Files processor was active and I emailed text+image and the target content didn't allow an image. Would the text portion fail? (Part of the issue with posting via email is the lack of feedback on actions - the user doesn't know if the email didn't post because of a system problem, an email problem, a permissions problem, etc. The only feedback is a successful post and even that requires an extra action, i.e. check the site.)

It may just be case for more detailed instructions. I'd be happy to contribute to that if you can suggest the right place to post it.

thanks.

Is it possible to match the email sender to a Drupal User by email address? I don't see a mapping in Feeds to User email, but if it's possible then I can see a path to providing feedback to users for at least successful mailhandler processes. Logging failures seems much trickier since there are so many points of failure.

I see it, in MailhandlerAuthenticateDefault.class you get the UID.

I'm sure there are many ways to go about this, but one method I thought about is related to the Feeds log since that is recording when a new node is created based on a Feed Node type. That's why I was wondering if there was a way to have Feeds map the sender to the UID.
