Open message in a new window
With this option checked, double-clicking a message in the email view will open it in a new window instead of the current browser window/tab.
Show email address with display name
With this option checked, it will display the messages with the display name specified at the time of creation of the email account.
Check this option to display formatted messages as the sender intended it. When disabled, formatted emails will be converted to plain text.
Display remote inline images
Formatted (HTML) messages can contain references to images which have to be loaded from a remote server. That can harm your privacy and reveal to the sender that you opened the message. This technique is often used by spammers to verify that your email address works and you can be sent more spam.
Display attached images below the message
Enable this option if you want image attachments being displayed below the message text.
After message delete/move display the next message
Controls whether the screen should jump to the next message in the list when opening an email message (not in the preview pane) and then move or delete it.
Default Character Set
Some email systems do not specify the character set when sending messages. In such rare cases the receiver (your webmail application) has to make an assumption about how to display the special characters and therefore uses this setting. Select the character set/language the majority of your email correspondents use.
