Djigzo Open Source Email Encryption

[randall]

Hi,

Just want to find if anyone have ever tried Djigzo Open Source Email Encryption with Zimbra?

The link is: Djigzo Open Source Email Encryption - Centrally managed open source email encryption at the gateway level and on mobile devices

It seems to be a pretty good solution for email encryption.

If anyone have tried, would appreciate knowing if its ok and how it's done. :-)

Thank you very much in advance!

Djigzo Email Encryption Gateway is a centrally managed email server (MTA) based on open source standards that encrypts and decrypts your incoming and outgoing email at the gateway level. Djigzo supports two encryption standards: S/MIME and PDF encryption. Djigzo is typically used as a store and forward server. It uses Postfix for the MTA part and is therefore compatible with any SMTP server including Zimbra. Djigzo can be installed with the provided VMware Virtual Appliance or it can be installed with one of the packages for Ubuntu Linux, Debian, Red Hat and CentOS.

The most typical setup would be run Djigzo as a separate server. All incoming email should be handled by Djigzo first and then by Zimbra to make sure that all email gets decrypted. Outgoing email from Zimbra should be delivered to Djigzo to make sure that email gets encrypted. Other setups however are possible, for example when combining Djigzo with a content/virus scanner.

Because Zimbra also uses Postfix it is possible to combine Djigzo with Zimbra. See the installation guide on how to configure the Postfix master configuration files.

Djigzo is built with Java so in principle it would be possible to integrate Djigzo with Zimbra (which is afaik also Java bases). This however requires some coding.

Not yet. But i might some day .

Do you think there is a need for integration?

I would love the ability to be able to flag certain emails as should be encrypted and others not.

That would require a Zimbra plugin that adds a special header. The Djigzo gateway can then detect the header and force encryption. I will see how hard it is to create such a Zimbra plugin.

That would be real cool especially if it was a additional button on the Zimbra Web Client. It is pretty trivial, IMHO, to add a button but what would the header need to be ?

I have been looking at the examples but I have not yet found a way to add a custom header to a message.

If someone knows how to add a custom header using a Zimlet to a new message I would be grateful.
