German email provider offering full inbox encryption is a new messaging service from the German company Heinlein Support GMBH which introduces several interesting features related to security and privacy, and based on Open-Xchange version 7.4.2.

The home page of the service is entirely in German, but not the webmail interface. It is available in several languages ​​including English, Spanish, Dutch, French and Italian. The only part of the web interface that is not yet available in other languages ​​is the Settings> page.

This is the page where you change your account type, password, or force email encryption to be sent to recipients who are not using PGP.

The first thing you should know is that the service is not free. It starts at $ 1 per month for three email aliases, 2 gigabytes of mail storage, and 100 megabytes for Office documents.

The company notes that you don’t have to worry about advertising – there isn’t any – and emails won’t be scanned, analyzed, or forwarded to third parties.

When you create an account – you don’t have to pay directly, as you can use it as a limited account for 30 days – you are only asked to provide the company with your username and password. , as well as your first and last Name. All other fields are optional and do not need to be completed if you do not want them to be.

The privacy protection page lists all data stored by the company and for how long it is stored. The page is only in German at the moment. Here’s a quick summary:

  • Web server: IP access, but no link between IP addresses and accounts. Stored for 4 days.
  • SMTP mail server: Sender and recipient, ID and size of the message. Stored for 7 days.
  • Pop3 / IMAP mail server: IP address and connection to the account. If emails are deleted, the message ID and size. If the mail is moved, the message ID and size, as well as the origin and destination folders. Stored for 4 days.
  • Administration: First and last name, possibly other data if entered when registering the account. If administrative changes are made, the IP address of the user who made those changes is saved for 7 days.

Data is stored primarily for verification purposes, to find out whether an email has been sent to a user if the user claims it was never received.

Inbox encryption

inbox encryption

One of the cool features of is the ability to encrypt the inbox. This is done using PGP which account owners must first install on their computer systems.

Next, you have to open Settings> Inbox Encryption on the website, to enable the feature.

Emails are encrypted using PGP. Subject, sender, and recipient emails will not be encrypted due to email functionality limitations.

Technically speaking, all simple incoming emails will be encrypted using your PGP public key once they arrive in your inbox.

These emails can only be read with your private key afterwards. Even can no longer access it.

It is theoretically still possible to access these emails, but only before they reach the inbox. Emails that are not encrypted by the sender can be read by anyone listening on any of the servers they pass through.

If you enable encryption, only emails will be encrypted. The address book, calendar and tasks also available on the messaging portal are not. However, the company plans to introduce encryption in these areas as well. offers another feature in this regard. You can force the use of SSL / TLS encryption. The consequence is that emails will only be delivered if the receiving provider accepts SSL / TLS encrypted connections. Otherwise, no email will be forwarded.

Drive and Office access


Another interesting feature is the integrated Drive module. You can save attachments in Drive to view or edit them directly on the webmail interface.

It works the same as Google Drive or Microsoft OneDrive.

All saved documents are displayed when you open the reader. You can click any to preview – if available – or select additional options that include editing directly on the page.

You can then print these documents, save them on the local system, or send them to email recipients.

Here is a list of all the types of accounts currently offered by Mailbox:

  • Mail for 1 to 3 e-mail aliases, max. 10,000 emails per day, 2 GB of email storage, 100 MB of office document storage.
  • Mail XL for € 2.50, 25 e-mail aliases, 10,000 e-mails maximum per day, 5 GB of e-mail storage, 100 MB of office document storage.
  • XXL Mail for € 3.50, 25 email aliases, 50,000 emails per day, 25 GB of email storage, 100 MB of Office document storage.

  • Office XL for $ 10, 25 email aliases, 50,000 emails per day, 50GB of email storage, 100GB of Office storage.
  • Office XXL for 25 €, 25 email aliases, 50,000 emails per day, 50 GB of email storage, 500 GB of Office storage.

You can make payments through PayPal, Bitcoin, bank transfers, sending money directly to the business or by bank draft.

Verdict improves email security in several ways without reinventing the wheel. To use the encrypted mailbox feature, it is necessary to install PGP and create a key pair. If you already have one, you just add your public key in settings and you’re good to go.

The privacy protection of the service appears to be excellent, with data only stored for as long as it takes before it is automatically deleted again.

The Drive component with its document editing option adds even more value to the service.

The only problem at the moment is the homepage which is only available in German, and the mailbox settings which is also only available in German at the time of the update. writing.

However, this is likely to change over time.
