Hosting the XML file on your own server

Host an XML file on your own web server containing the mailbox email server data.

This XML file must follow a defined syntax, which is explained in detail in the Mozilla Wiki. You can specify the domain, incoming and outgoing email servers including ports, and even define encryption methods and authentication mechanisms.

mailbox provides a ready-made file with all required settings, which you can download from the following URL:
https://mailbox.org/mail/config-v1.1.xml

To use this configuration for your custom domain, enter your own details in the following three header fields:

• <domain>
• <displayName>
• <displayShortName>

Then save the file in the appropriate location on your web server.
