Thanks Ed! It seems my version of mutt (1.5.21) has the
features/trash-folder
compiled in, yet I didn't yet set the respective variable in the
config file. Will test that and get back to this list if there is
still questions open. Thank you also for hacking out the option below,
which seems very cool as well!
