Thanks for your answer.
I added the code in config/plugins.js, and have “strapi-provider-email-nodemailer” version ^3.6.8
I’m getting the following error, which doesn’t appear without the change, I couldn’t debug it, do you have an idea where it comes from
[2022-04-13 15:46:13.188] debug: 
Server wasn’t able to start properly.
[2022-04-13 15:46:13.190] error: provider.init is not a function
