Efficient and secure way to archive electronic mail.

Piler is an open source solution that enables email archiving at an organisation.


Piler solution provides a number of benefits for an organisation:

  • Ensuring continuity of access to and restoration of data.
    Piler provides a secure central repository of messages, including the provision of necessary information, even if the mail server is down.
  • Rules and obligations
    The regulations for government and local self-government organisations require that electronic messages are retained for several years from the moment of data processing. To meet these requirements, Mailpiler saves messages and makes them available in the legally required period.
  • Storage and search for messages
    Piler saves storage space by compression and smart deduplication. It also allows you to offload data from the mail server to piler, thus minimizes storage costs.
  • Security
    Piler eliminates the risk of losing messages as a result of malicious and intended activity of users. "Peter stopped working for us over a year ago. Unfortunately, I cannot help you in this matter because he had deleted his messages before he left"...

Mailpiler solution perfectly complements the Zimbra email and groupware system. We integrate both systems and offer a dedicated zimlet to expand the Zimbra functionality by adding the archiving module.
