Would like to create something like Craigslist in terms of its anonymous emails so that Logged-in users can send email from the site. Once they do, their email will be changed to firstname.lastname@example.org instead of their original email. This is to prevent other users from knowing the real email of the authenticated users.
Other users should still be able to send them email with the email@example.com as To and that reply would be saved on the Users's profile.
How would you go about implementing this? The module I found that's close, but not sure how it works is Mailhandler with Singlebox . But there's rarely any documentation for it. Do you recommend other solutions?
