This is what authenticated SMTP is for. (preferably done on port 587
rather than port 25, to avoid blocks or interception proxies)
(Though I have little time for those who harp on about blocking mail
from dial pools; it's certainly not an option for us (would piss off
too many of our users), not to mention that relatively few ISPs are
actually capable of providing reliable mail smarthosts.)
