The Standard in Professional Email Archiving

Compliance Fingerprint

Businesses are faced with the challenge of meeting a growing number of regulations on email compliance (e.g. HIPAA and FERPA in the United States or GDPR in the European Union), eDiscovery, and other legislation. We believe that in order to do this, they have to be in a position to archive email in a central, complete, and secure manner for any given length of time, and ensure that it can be located again at a moment’s notice.
On 25 May 2018, the General Data Protection Regulation (GPDR) becomes effective in the EU. The new regulation represents a broad-reaching harmonization of data protection laws in the EU. In the past, regulations varied greatly from country to country within the EU. The end goal is standardization, and a simpler process, but there will be new challenges in understanding the regulations, and determining the most effective way to comply with them. The new regulations affect all EU companies –and many of the companies outside the EU that collect or utilize data of EU residents.

Businesses can benefit from all advantages of modern, secure email archiving with MailStore Server – MailStore can help support certain GDPR requirements. The software creates 1:1 copies of all emails in a central email archive to ensure the security and availability of any amount of data for years to come.

Compliance Features to Support Your Data Governance


MailStore Server enables the complete archiving of all email within a company. For example, email can be archived before being forwarded to employees’ mailboxes – your foundation to guarantee a solid and auditable email archive.

Authentic Archiving

An archived email is identical to the original email in every respect and can, if necessary, be restored from the archive without losing any information.

Secure Storage

MailStore Server prevents archived data from being tampered with by generating SHA hash values from email content and by using internal AES-256 encryption.

Secure Exports

A cryptographic signature that can be added to exported emails ensures that exported emails remain protected from tampering, even outside of the archive.

Retention Policies

By default, users cannot delete emails from the archive unless the administrator has explicitly changed this permission. Sophisticated retention policies that override all user privileges can also be defined.
If the Legal Hold function has been enabled, no emails can be deleted from the archive, regardless of all other possible configurations of user privileges and retention policies.


MailStore Server uses an integrated auditing function to consistently log changes and events, which can be defined by the administrator.

Auditor Access

A special auditor user type allows external auditors to access the archive. All actions performed by this user type are always logged.
