Recently I got interested in the mailing system and explored some stuff, and finally decided to design a Temporary E-mail service as my first work in mailing service.
FlushMail - Anonymous Temporary Mail Service [Support files/attachment and immediate mail disposal]
You can access this here: flushmail.live and the link in the first comment.
Please leave feedback in the comments. If you would like a detailed blog on this project/mailing system or any other topic, feel free to let me know in the comment section.
I am working on its documentation part, ASAP it gets ready I will update that. I am going to extend this one project and have some ideas to work on an email privacy tool. If anyone want to collaborate please give a reply
