[alatouz]

here is my setup ` - MAIL_SMTP_ENABLE=TRUE

• MAIL_SMTP_VARIABLES=-S smtp-use-starttls -S smtp=smtp://smtp.free.fr:587 -S smtp-auth=login -S smtp-auth-user=xxx.xxx -S smtp-auth-password=passxxx -S from=xxx.xxx@free.fr
• MAIL_TO=xxx.xxx@free.fr
• MAIL_WHEN_SUCCESS='TRUE'
• MAIL_WHEN_FAILURE='TRUE'`

here are the error messages
