Recommendations for FREE email hosting for custom domain
I've googled around for free hosting for custom domains, and I've seen that some of the lists are inaccurate, misleading and/or out of date.
What is the current best option for free email hosting for custom domains?
This is for something largely unimportant. Hell, I am considering using mailinator (free) for it if that gives you an idea. (No customers will send information to this domain. No important email will be sent to the domain.)
What are the current options? What is the best option?
