This is a public catch-all mail service. Catch-all means that all e-mails are accepted and delivered, regardless of the username part of the e-mail address. But this is not a usual catch-all mail service. This service allows you to use any third-level domain. It is intended for testing purposes.
E-mail addresses consists of two parts: a username (local part) and a hostname (domain part), e. g. user@example.com. This mail services allows you to think up any username and use it without registration. It is also possible to specify any sub-domain (third-level domain) as part of the hostname and choose from a given set of domains (second-level domain).
For example, if you send an e-mail to john.doe@acme.8bx.de, it will be delivered to the mailbox acme@8bx.de. Note that the chosen sub-domain name of the e-mail address becomes the username part of the mailbox name. If you send another e-mail to jane.smith@acme.8bx.de, it will be delivered to the same mailbox, because of the eponymous hostname. This way you can create any number of email addresses associated with a single mailbox.
Visit https://m.ailbox.de/ and log in using the name of the mailbox as username and the sub-domain name as password. For example:
Username: acme@8bx.de
Password: acme
Yes. You can protect the mailbox with your own password. Log in with the default password of the mailbox, go to settings, select “Password”, and set a new password.
No. If you try to send an e-mail, you will get an authentication error message.
You can use one of the following domains: 6av.de, 7uv.de, 8bx.de and 9xe.de.
Of course! You don’t need to try them: abuse, hostmaster, info, marketing, noc, postmaster, sales, security, support and webmaster. They won’t work.
Please do not abuse it and use it wisely. Otherwise I will shut it down.
