[image] Disabling starttls or certificate verification does not work any more PR has been merged earlier today so by using the tests-passed branch you should be able to disable TLS as before :slight_smile: Thanks @loic , I just updated and for me it still doesn’t send emails. I use SMTP port 2…

Try adding just this line to your app.yml DISCOURSE_SMTP_OPENSSL_VERIFY_MODE: none Don’t add the START_TLS line

OK, since sending emails no longer works without SSL / TLS, can someone please help me reconfigure it? From here : Try to open a connection to your smtp server via openssl: (telnet, nc etc. are not installed inside the container.) Fiddle with some different settings until you succeed with a conn…

Can you configure your mail server to use port 587 (TLS or none, see which works) and then try this and rebuild discourse DISCOURSE_SMTP_ADDRESS: smtps.aruba.it DISCOURSE_SMTP_PORT: 587 DISCOURSE_SMTP_USER_NAME: myemail@domain.info DISCOURSE_SMTP_PASSWORD: “password”
