Ciao, ho provato con entrambe le opzioni. Ancora non funziona:
DISCOURSE_SMTP_ADDRESS: REDACTED
DISCOURSE_SMTP_PORT: 25
DISCOURSE_SMTP_USER_NAME: REDACTED
DISCOURSE_SMTP_PASSWORD: REDACTED
DISCOURSE_SMTP_ENABLE_START_TLS: false # (optional, default true)
DISCOURSE_SMTP_OPENSSL_VERIFY_MODE: none
DISCOURSE_SMTP_AUTHENTICATION: "login"
Ricevo ancora certificate verify failed (self signed certificate).
