Return of Reckoning

I seem to have accidentially clicked the "report spam" button on a mail, causing it to immediately vanish - along with all its content.

Is there any way of retrieving such mails? It has not been returned to the sender - which I kinda hoped it would have been.

If mails reported as spam are irretrievably lost, would it ve possible to add a "Are you sure?"-warning, like there is attached to the "delete" button?

We don't know how to call those functions if they already exist in-game (same issue with crafting respec). The mail is deleted from the DB when that happens, so it's gone. Seems pretty rare, guess you'll be more careful clicking on things in the future.
