Lemarinel Sébastien Posted September 10 Posted September 10 Hi, When we use a custom SMTP withh TLS or SSL Invision is using by default the "AUTH LOGIN" but in some case this is not supported by the SMTP server. Example Protonmail SMTP only support "AUTH PLAIN". See my comment here: Neureka 1
Neureka Posted October 7 Posted October 7 I have the same issue when trying to use Protonmail's SMTP service. Proton only supports AUTH PLAIN. Can we get an option to select the type of authentication to use?
