The class needs to know the size of files included in the messages that you send just to check that the messages were fully read. It seems it is not possible to get the file size of those remote files you are using due to some circumstance in the remote HTTP server.
I can add a workaround to the class but I have some priority tasks to work, so I am not sure when I will be able to look into this.
I suggest that you retrieve the remote files that you pass to the class using URLs and store those files in local files in your server. Then pass the paths of those files to the MIME message class and it will work.
Can you please try this and let me know if this works?
