How to create your own mail service?

Question

Email

Hello Toaster. I want to create my own mail service, I made personal mail servers based on iRedMail. But there is a question - how to create your own service? I have already found the client (mail web), the domain too, VPS too. I wonder how to implement registration and automatic registration of a mailbox, how to integrate payment? Thank you.

Answer 1

1. Option (learn php|net|python sql and write it yourself)
2. Option to pay someone who can do it.
PS you have experience in monetization of services, what is your feature? What kind of storage do you offer customers?
