Not right now, because any value at all is treated as "true" (and I'm pretty sure even empty value). I suppose the best solution would be to finally change all the passdb/userdb/plugin boolean values to actually support "no" value as not being enabled. It's something that we're thinking about for Dovecot v2.3.

It would probably also be useful to add support for removing a field entirely, such as returning "-proxy" (where the =value would be ignored). I'm not entirely sure how useful that would be though.
