Trying out Dynu.com as the old provider is expensive. Transferred domain for $11 and now have free DNS. Old place was $60/yr. Using Dynamic DNS services. They also have a number of email services such as outbound/inbound relay. I use AWS for outbound (free) but now use Dynu.com for Inbound ($10/yr).
If experiences please share. Just wanted to point out stuff that is cheap and sometimes hard to find (like inbound relay).
