How to manage (create/delete) Email addresses programmatically?

I am building a web application that will also allow my users to register/transfer a domain and manage email addresses through my application. However, I'm not exactly sure how to do that yet. I think there are services with APIs 开发者_开发知识库that will allow me to register domain names. However, working with DNS, MX records, email addresses and running an email server is something I've never done before. What do I need to know about automating this process of managing email accounts, and what sorts of solutions already exist?

for the email address part, have a look at How to communicate with a mail server through a web application

the dns part is pretty much the same, but you need a dns authoritative server with a database backend, such as powerdns (database configuration docs) if you don't want to run the dns servers yourself, powerdns also offers hosting with API access
