How many mail accounts do you have set up in Thunderbird? Are you using pop mail accounts that are setup to use a Global Inbox eg: 'Local Folders' mail account? Check the filter. Is the filter set up in the correct account? eg: Filters for: mail account name which may be your email address. Is the email being forwarded to another mail account which you have setup as a mail account in Thunderbird? Please post info: Help > Troubleshooting Information click on 'Copy text to clipboard' button In this forum question, right click in a 'post a reply' text box and select 'Paste' You can edit/remove all info on fonts and printers but nothing else.
