How to create an email address with a domain of example.jp

example.jp is another type of domain reserved for use in closed networks and experimental use (defined in RFCs, etc.).

example.jp If you want to create an email address for the domain, you need to build a completely closed (non-Internet) network with a DNS server and a mail server (POP3, SMTP, respectively).

However, creating the above environment is useful for studying, but it is not directly related to web applications, so it may be better for you to obtain a valid email address yourself and use it.

If multiple addresses are required for testing purposes, for example, in Gmail, you can add + followed by + and use it as an alias for a single email address.

(Example)
[email protected]
[email protected]
[email protected]

One thing to note is that you should not use real email addresses or domains that you do not manage, even for testing purposes.
