Hi, I use Outlook.com e-mail service on my own domain (via Windows Live Domain). I really like the service but what bothers me quite a lot is that when someone sends an e-mail to me, sometimes it returns back to the sender as undeliverable, without me knowing a thing. It only happens sometimes and only with an e-mail from certain senders. Has anyone come across the same issue?
My DNS is set correctly.
