"SafetyAnswer"'s e-mail address anonymization aims to reduce the risk of information leakage by not collecting the sender's address.
Many existing email address anonymization tools are used to fake email senders' own email addresses. Anonymization of "SafetyAnswer" has a very high industrial value effect.
The discovery of the fact that both sending and receiving e-mails can keep their addresses secret by exchanging through one "Known address" is great.
There is no existing concept that replaces the email address and forwards the email. It is provided by "SafetyAnswer" only.
It is hoped that it will be used in various application fields, not limited to examples of how it has been devised.
Also, "SafetyAnswer's" mail forwarding and reply works similar to mail address routing.
With the current e-mail system, even if mail is sent repeatedly by sending mail, the mail cannot be sent back by following the route that was forwarded in reverse.

However, even if mail is forwarded many times using "SafetyAnswer", the mail that is replied from the last recipient will be sent back in the reverse route exactly back the route that was followed by mail forwarding.

In mail forwarding using "SafetyAnswer", mail is always sent back via the forwarding point that has passed. Therefore, it is also possible to receive and share the contents of the reply mail from the forwarding destination at the forwarding point.
The ability to distribute e-mail with such specifications is a new characteristic that has not existed in the e-mail system so far.
Many fields that can be used in the future are found and We expect them to be used greatly.
