That's indeed true, but you'd also lose threading from those sucky
clients. I don't have any statistics handy but I'd say that it wouldn't
matter, though, so yup, my vote goes to completely removing checks for
subjects.

That won't be much effective, I'd say, but surely better than nothing.
I'd rather see a more robust solution, though.

I meant that entirely skipping the processing of subjects seems to be
easier, but I haven't looked at the Dovecot code.

Oh, they aren't? I should probably re-read the draft then.
