When you delete email from the Horde webmail client, the email does not move to your trash, it still shows up in your inbox, with a strikethrough. This guide will show you how to delete it from your system

Within your Horde webmail client
Click the Gear icon at the Top Right
Select Preferences
Click Mail
Select the link for Deleting and Moving Messages
Place a checkmark next to:
Move deleted messages to your Trash mailbox instead of marking them as deleted in the current mailbox?
Click Save
Return to your Inbox, select your previously deleted emails, and delete them again. Now your messages will be moved to trash
