SparkMail for DSM

0.3.1-0012

The web client, inside DSM: the same smart inbox as on the Mac, in a DSM window.

Two native DSM packages: a full mail server for your NAS and the SparkMail client that opens right inside DSM. No Docker, no licences per user.

Questions and answers

Which NAS do I need?

Needs a Synology with an Intel or AMD processor (x86_64), DSM 7.2 or later and 2 GB of RAM — 4 GB with the antivirus on.

What if I cannot add a package source?

No access to Package Sources? The same SPK files can be installed with Manual Install; Package Center then lists the missing packages to install first.

How do I check the downloaded file?

In Terminal, run the command below and compare the result with the SHA-256 fingerprint on the right. If a single character differs, do not open the file and write to us.
