mccs

mccs stands for Mail, Calendar, Contacts Setup.

mccs is a web page you host for the customers of your mail service. They type their address, pick a device and get a short guide with every value ready to copy: mail (IMAP and SMTP), calendar (CalDAV) and contacts (CardDAV) on Windows, macOS, iPhone, iPad and Android. It never asks for a password and stores nothing.

Start here:

• Install mccs: from the repository with Docker, or with Node alone.
• First run: what to check once it answers.
• Configuration: every environment variable and its default.

Free, for good. MIT licence, no paid edition.
