When you send a message, so far as I know, you have to save that message and then it would give you the option to send that message.
By default, that saved message is saved in your home folder as the file that is simply called
sent
Now, if you send another message, that new sent message is added to the end of the sent file.
I do not want that sent file in my home folder.
So I created a script that upon boot will delete this sent folder.
Other users may want to do this or do other things with the sent file.
Your choice as to leave it or remove it or place it somewhere else.
