Please tell me when deleting a message from a photo, the photo is also deleted from the /ow_userfiles/plugins/mailbox/attachments folder? just over time a bunch of pictures accumulate there.
Deleted messages are being deleted on the fly, this means all messages and files are still in there, messages too, users are unable to see them. I will add a new option to fully remove the messages from the database and attachments directory when both users delete the message or when the user clicks on "Delete for everyone".
