Problem

After sending messages with an attachment (pictures), they are not in the sent folder

Context

If the e-mail contains only text, it is displayed as sent in the sent folder, but when he wants to send photos, it cannot be seen in the sent folder, but the message itself reaches the recipient. This is problematic because you cannot see e-mails with attachments in the history of the conversation with the client.
