The Lua management function 'VPOP3.DeleteMessage' marks a specified message to be deleted, or removes the deleted flag.

Messages marked to be deleted will not be deleted immediately, but only when that mailbox is 'purged' from an IMAP4 client.

VPOP3.DeleteMessage(username, folder, UID, delete);

• username is the username from VPOP3.GetUsers
• folder is the folder from VPOP3.GetFolders
• UID is the UID from VPOP3.GetMessages
• delete is true if the message is to be marked for deletion or false if that mark is to be removed.
