I apologize if this isn't the right place to ask, but due to an automatic list import malfunction, some of my client's email address settings were misconfigured in his Web host's control panel, and an option to delete all messages on the server was checked while no forwarding addresses were specified. The Web host tells me because this option instantly deletes all messages, there is no trace on the server and no way to recover any of the messages. This is very problematic as you might imagine. Could there possibly be a solution the Web host isn't aware of?

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form.

Maybe with some good old digital forensics/file recovery you would be able to recover the files, but then we are talking shutting down their server and manually recovering it to an external drive (providing none of that diskspace got overwritten with a new file).
I highly doubt they are willing to do that, it's very costly.
(I would say recover from backups, but the chance is they do not have any (complete) backup because of the short timespan)
