Best regards, Christine February 26, 2020 at 1:30 pm #247594 StefanoKeymaster Hi, the SMTP interface is implemented in a provided library by WP. So, if you specify tls as protocol that library should use the better one. As alternative, install an SMTP plugin which may use a different library. Let me know.
