Description Guilherme de Almeida Suckevicz 2021-04-30 17:50:59 UTC 
Deleting an attachment of a decrypted encrypted message stored on a remote server (e.g. an IMAP server) causes KMail to upload the decrypted content of the message to the remote server. This is not easily noticeable by the user because KMail does not display the decrypted content.
