Email account connection info on edit user page and after creation

A user requested an easy way to see how a mail user should connect to their server. I believe those details get included with the post-creation email, but for users that don't have a recovery email that'd be a non-starter.

I think it'd be useful to have it be a collapsible field on the user edit page, but the user requesting it wanted it to be on the result page immediately after creation. That also makes some sense.

Specifically, this would be the name of the server, the protocols available (IMAP/IMAPS, POP3/POP3S, SMTP/SMTPS, and their ports, the username, password, etc.)



There's a button already to re-send the signup email .. would that help? Or perhaps just display the signup email on a collapsed tab on the Edit User page?
