Compliance Features

Businesses are faced with the challenge of meeting a growing number of regulations on email compliance, eDiscovery, and other legislation. In order to do this, they have to be in a position to archive email in a central, complete, and tamper-proof manner for any given length of time, and ensure that it can be located again at a moment’s notice.


MailStore Server enables the complete archiving of all email within a company. For example, email can be archived before being forwarded to employees’ mailboxes.

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.

Tamper-proof 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.

Tamper-proof 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

In principle, users cannot delete emails from an archive unless the administrator has explicitly changed this permission. Sophisticated retention policies that override all user privileges can also be defined. These policies can help to meet the EU’s General Data Protection Regulation (GDPR).

Legal Hold

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 periods.


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.


The archive search can also be performed on a company level as an eDiscovery procedure. This makes it possible to search through a company’s entire email portfolio in a single step.

Export Features

MailStore Server does not restrict businesses to a proprietary file format. All archived email can be exported in a single step at any time.
