Changing the default character encoding and displaying of remote resources/images

You can change the default character encoding (UTF-8) and toggle the displaying of remote resources/images in Roundcube and Webmail Classic.

The process will vary depending on your webmail client of choice:

Roundcube

To change the default character encoding or toggle the displaying of remote resources/images in Roundcube, you need to open the Settings task from the main menu, select the Preferences setting, and select the Displaying Messages option.

The drop-down menu from the Advanced Options subsection allows you to choose another character set as default for messages without a defined character set.

The Allow remote resources (images, styles) drop-down menu allows you to specify how Roundcube should handle remote resources. You can choose from the following options: never, from known senders (default), and always.

In Roundcube, you can also use the Display HTML and Display attached images below the message checkboxes to enable or disable the HTML formatting when reading messages or the displaying of attached images below a message you are reading. These options are enabled by default. If you prevent HTML formatting, you will view the content of messages in plain text. You can enable HTML formatting for a particular message via the Display in HTML format button labeled HTML (with a landscape icon in front of it) below the message headers in the Elastic theme or labeled <> on the right of the message headers in the Larry theme.

Additional details on the messages displaying options for Roundcube are available in the Preferences article from its official documentation.

Webmail Classic

You can select the default character encoding or toggle the displaying of remote resources/images in Webmail by clicking on the Options tab from the main menu and going to General Options.

Use the Default encoding drop-down menu if you wish to change the default character encoding (UTF-8) for all messages. If a specific message that you are reading is not decoded properly, you can change the character encoding for it temporarily via the Encoding drop-down menu below the Subject of the message.

The Display external HTML graphics drop-down menu allows you to enable or disable the display of images that are not attached to the message, but are hosted on third-party servers.
