Mailtrain App

Discontinued

Please note this app is not available anymore since upstream development has stopped.

About

Mailtrain is a self hosted newsletter app.

VERP handling

VERP is a feature where bounces are sent back to special addresses. Mailtrain supports VERP and can be configured to process these bounces and automatically unsubscribe addresses that are bouncing.

Changing Email "from" Address

Cloudron's email server does not allow apps to send emails with arbitrary FROM addresses. This is a simple security measure that prevents apps from unintentionally sending out emails that they are not supposed to send.

Cloudron assigns location.app@domain address by default to apps. To change this email address, follow the instructions here.

External mail server

To revert from an external email server setup to the Cloudron setup, set the SMTP Hostname to localhost and then restart the app. This will inject the Cloudrons SMTP credentials automatically.

Customizations

Additional settings can be added to /app/data/production.toml using the File manager.
