Nextcloud with GoBD-Compliant Email Archiving: How to Make It Legally Secure

Why GoBD archiving matters for Nextcloud users

Nextcloud is the leading open-source platform for files and collaboration: but the basic installation does not archive emails in a GoBD-compliant way. Companies handling business emails through Nextcloud must meet tax retention requirements: audit-proof, immutable, with full-text search and statutory deadlines.

The GoBD requirements at a glance

• Immutability: Archived emails must not be modified or deleted retroactively.
• Completeness: All business-relevant communication must be captured: including attachments.
• Retention periods: 10 years for booking records, 6 years for business letters.
• Full-text search: Archived data must be findable for audits.
• Documented immutability: Audit security must be technically provable.

The problem: Nextcloud is not an email system

Nextcloud manages files, calendars and contacts: but email archiving is not part of the feature set. Anyone handling business emails through Nextcloud needs a separate solution. This is where Souvera comes in.

Souvera Mail Archive: GoBD-compliant, integrated into Nextcloud

Souvera Mail Archive extends your workspace with audit-proof email archiving:

• Immutable storage: Sealing technology with Merkle chain: any modification would be technically detectable.
• Statutory retention periods: Automatically configured for 6 and 10 years.
• Full-text search: Search the entire archive in seconds.
• GDPR-compliant: Archiving in German data centers, no third-country transfers.
• Integrated: No separate system needed: the archive runs inside your Souvera workspace.

Who is this relevant for?

• Law firms: Retain client communication in an audit-proof manner.
• Retail: Store business letters and orders in a GoBD-compliant way.
• Public bodies: Meet file management and data protection requirements.
• Every company with bookkeeping: Emails with invoices and receipts are tax-relevant records.

Conclusion

Nextcloud + GoBD archiving = legally secure email management. Souvera Mail Archive integrates both seamlessly into your workspace: audit-proof, GDPR-compliant and without additional infrastructure.
