General Questions and Basics
This section clarifies fundamental questions regarding functionality, terminology, and security in Electronic Legal Communication.
What is a SAFE-ID? - Please click
In EGVP, a SAFE-ID is the unique identifier (address) of a mailbox in the SAFE directory service, used to address and deliver EGVP messages.
Every participant (e.g., court, authority, lawyer, or notary) automatically receives such a SAFE-ID when creating an EGVP mailbox, under which they are reachable in the directory service.
This ID usually looks something like this: safe-sp1-1400589659747-015539967 and is unique throughout Germany.
The SAFE-ID is also required to activate, for example, a special electronic authority mailbox (beBPo) – without this ID, no application can be submitted to the beBPo verification office.
Can De-Mail accounts and EGVP accounts communicate with each other? - Please click
No.
Because EGVP and De-Mail are based on separate, legally and security-technically independent platforms using different protocols (OSCI vs. SMTP/IMAP with S/MIME) as well as trust ecosystems, and neither a gateway nor an intermediary service is technically or legally prescribed, messages can only be sent and received within their own respective systems.
Can eBO accounts and beA accounts communicate with each other? - Please click
Yes.
The eBO ("electronic citizen and organization mailbox") is a secure transmission method within the framework of electronic legal communication. Since June 1, 2022, the eBO has been integrated into the EGVP infrastructure and is therefore also addressable in the beA system (special electronic lawyer mailbox).
How are my files and messages protected during transmission and storage? - Please click
The messages are encrypted from the moment of sending, and the files on the Safe system are protected by the EGVP security concept.
Access rights are defined based on a role concept so that data cannot be read, copied, changed, or deleted without authorization after storage. All security and data protection-relevant accesses are logged, and access protection is increased through the use of a firewall.
Where can I find more information about the basics and functionality of ERV communication? - Please click
Detailed basics and current news from the judiciary can be viewed in the ⇒ Justice Portal . Current guidelines can also be downloaded there.
Account and User Management
This section addresses questions regarding the management of user access, rights, and authentication methods.
Can I share an ERV Portal access with multiple users? - Please click
No, account sharing for the ERV Portal is not supported.
Due to Two-Factor Authentication (2FA) and other security measures, every access is personal and not intended for shared use. If the ERV Portal is to be used by multiple users, a separate access must be ordered for each individual.
Why can't a user use the ERV Portal even though they were invited? - Please click
In this case, it is not due to a missing registration, but due to missing permissions in the ERV Portal. An administrator must manually assign the appropriate permissions.
How admins can assign permissions:
- Settings → User Rights
- Select the row of the affected user
- Mailbox access → Edit
- Activate the desired access permission via checkbox in the list of SafeIDs
- Click on "Close" to save

Can I change or adjust my Two-Factor Authentication method? - Please click
Yes, the Two-Factor Authentication method can be adjusted via the settings under User 2FA in the online portal.

Here, a method can be set as primary, deleted, or backup tokens for login can be retrieved.

Troubleshooting and Technical Issues
This section provides solutions for specific error messages and technical problems.
What to do if emails with attachments arrive as "gibberish" with a .json file? - Please click
Cause: This happens when the sender's mail gateway signs or modifies the message content before sending it to the Mentana Gateway. This prevents the attachments from being correctly assigned.
Solution: The sender's IT must ensure that the message is forwarded unmodified on their mail gateway to the Mentana Gateway. This cannot be fixed by our IT or service.
A setting in a message is overwritten/not applied during sending? - Please click
If settings that were correctly configured in the Gateway are overwritten during sending, the message is needed as a file to trace the process.
Please send the message as a .eml file or the message header, once in the form as it was sent, and once as it was received. If the Add-in is installed, an Add-in log is also very helpful.
Incoming message is not in the functional mailbox. How do I receive the message? - Please click
Delivery attempts & Escalation: The Gateway tries up to five times to deliver a message. If this fails, the message is forwarded to the stored Postmaster address and ultimately lands in the folder C:\Program Files\Mentana\Gateway\data\Failed-Messages as a .eml file.
Check steps:
- Check connection between Gateway and mail server.
- Ask Postmaster if a forwarded message was received.
- Check the sending period in the Gateway log.
Support: If the message is still missing, please send us the EGVP Message-ID of the message.
Why was my message aborted due to an invalid filename? - Please click
Cause: Sending is aborted if a file attachment bears an invalid name.
Checklist for valid filenames:
- Only letters and numbers (umlauts allowed).
- No special characters.
- Use only
-(hyphen) or_(underscore) as separators. - Maximum length: 90 characters.
- Only one dot
.before the file extension.
Solution: Rename the file accordingly and try sending again.
What does error 9999 mean in the Mentana Gateway? - Please click
Cause: Error 9999 indicates a temporary disruption in the sending process where a required resource (e.g., the SAFE system of the judiciary) was briefly unreachable.
Solution: Current Gateway versions include an automatic retry function. Please wait and try sending the message again after some time. If the error persists, check the reachability of the recipient.
What does error code 150067 mean and how do I fix it? - Please click
Cause: Error 150067 means that the attached xJustiz file could not be read because it is faulty or non-compliant.
Solution: Check the file with the official ⇒ XML-Checker of the judiciary and adjust it if necessary.
Mentana Outlook Add-In is deactivated by Outlook: What can I do? - Please click
Cause: Outlook deactivates Add-ins that it considers too slow. This can happen if the Add-In checks emails in the background over a slow connection to the mail server.
Solution: Outlook can be configured in the Windows Registry so that the Mentana Add-In remains permanently active. This should only be performed by the IT department. Detailed instructions can be found at Microsoft under:
How can I request an eEB (electronic acknowledgement of receipt)? - Please click
In the Electronic Court and Administrative Mailbox (EGVP), an electronic acknowledgement of receipt (eEB) can only be requested by the judiciary. For other user groups, such as citizens or organizations, requesting an eEB is not intended.
