I am in the process of conceiving this idea of a webApp when can be termed as a completely new take for providing Email Service to the consumers on Domains that I own. The idea is similar to what Yahoo does by providing me
[email protected] email address or the same with gmail etc. Apart from the whole infrastructure the main concern I have is how to have a list of critical / important and security related email addresses that are not given out to the consumer.
Is there any kind of exhaustive list of this kind available.
