Your company's domain or your email address may have been blocked. You can ask that their IT folks add your domain and/or email to their "whitelist."



But my experience has been that getting unblocked is not easy. I was in in regular contact with maybe ten people from an organization, but one could not receive emails from me. We ended up corresponding through my antediluvian Hotmail account!
