Notes and troubleshooting

Despite using auto dark mode, Posteo webmail does not adapt to my device. Why?

Some browsers do not adjust light or dark mode according to the selected device settings. In this case, in the browser settings, specify that the browser should automatically follow the device settings.

Why are some emails brightly displayed even in dark mode?

In HTML emails, the background color is set by the sender of the email. The background color remains the same even if you activate dark mode. Many newsletters and other HTML emails therefore still have a light background even when dark mode is activated. However, more and more newsletter senders already comply with dark mode settings of the respective recipients. If you are bothered by a light newsletter, feel free to contact the sender and ask for an adjustment.

How can I change the font size in dark mode?

The font size in dark mode corresponds with the color and contrast level that has been selected for the interface design. You can change the color and contrast level in Settings via -> Preferences -> User Interface -> Interface skin.
