Short answer: yes, for non-local addresses.
Long answer: As described in section 39.30, what happens is that the
address is run through your routers in verify mode. If any router
accepts, verification succeeds. In *typical* configurations, non-
local addresses will be accepted by a dnslookup router as long as the
domain part has a valid MX or A record. Local addresses will
generally be accepted by the local delivery router only if the
username is valid as well.
