Since you didn't provide an example DSN or even anonymized logs of a bounce, we can't guess-- in general you'd discuss a specific bounce message with the postmaster of site which bounced it. As for hotmail.com, they can't even be bothered to make postmaster@ work: http://www.rfc-ignorant.org/tools/lookup.php?domain=hotmail.com ...which means they're sufficiently broken that you should expect mail failures.
