Peu fiable, a corrompu les messages entrants d'un compte IMAP en écrasant un certain nombre d'information
after installation, the date received file has been corrupted for about 10 messages , replaced by date/time when the module started operating
Never mind, I have suppressed then recreated the concerned account

The add-on does not overwrite any message information. It only READS the headers of the messages and parses them to display them in a more simplified way. May I ask what information has supposedly been overwritten?

Edit: Thank you for providing some details. The "module starts operating" when you click on any mail or open a folder that has the spam score column enabled. It then reads the contents of certain headers to display the relevant information. No writing takes place at all. Perhaps another add-on is installed that is causing these problems, or the mail server has changed the headers. If the error is reproducible with the Spam Scores add-on, please open a new issue on GitHub for further discussion and to help fixing the problem: https://github.com/friedPotat0/Spam-Scores
