Problem script e-mail heading to dev-email@flywheel.local

Hi,

I recently used Local bu Flywheel to develop my website in local. Since I migrated online, I get every day an error e-mail from OVH saying that there is a problem with mails heading to rfc822;dev-email@flywheel.local. I have no idea why mails are sent to this adress since I changed every e-mail in wordpress (not sure I did it when I configured my website in local though).
Do you have any idea where I could find the file containing this setup adress to change it ?

Thanks forward
