I have my email set up such that when I message a client from the contacts tab they get an email with my catchall@ as the reply-to. I assume that the message-ID in the header is what tells odoo that the reply should be posted as another message on the same contact.

What happens though, when a client decides to compose and email from scratch and send it to catchall@ ? Obviously odoo doesn't know where exactly to put it, but is there a generic place for it to go?

I know you can set up the claims module to catch such emails - but I want to have odoo ready for any eventuality. If a freshly composed email is sent to any of the aliases that odoo uses it should appear somewhere right?
