I have updated the plugin hook.php version 3.0.0 for the compatibility version GLPI 10, with the code that @mat44444 has shared. I'm testing for a while, you should do the same. hook.txt Rename it txt to php, and replace it.
For now, the only problem I got is that in notimportedemail.php I'm getting: "REASON OF REJECTION: Failed operation" but actually the ticket is already imported and added correctly as a followup depending mailcollector/mailgate/receiver as what you want call it.
