But perhaps that's not a thing.
I retract my claim that is makes no sense. It can make sense and that's why --auto-key-retrieve also does a lookup by email address on WKD. > > The equivalent for automatic look-up of keys when verifying signatures is > > --auto-key-retrieve. > > Thanks, but the manpage doesn't include DANE as one of > the lookup methods for that option.

So what you actually want is that --auto-key-retrieve also does a DANE lookup or in fact all kinds of lookup supported by --auto-key-locate. Did you check that it not already does this (even if the man page doesn't mention it)? If yes, then I'd say submit a request for this feature at https://dev.gnupg.org. Regards, Ingo
