TLS not working

[plancked]

Hi,

I cannot get TLS to work.
I've created a self-signed certificate using:
openssl req -x509 -newkey rsa:4096 -keyout /opt/postal/config/smtp.key -out /opt/postal/config/smtp.cert -sha256 -days 365 -nodes

and added the config:

smtp_server:
  default_bind_address: "::"
  tls_enabled: true

also tried:

smtp_server:
  default_bind_address: "::"
  tls_enabled: true
  tls_certificate_path: /opt/postal/config/smtp.cert
  tls_private_key_path: /opt/postal/config/smtp.key

But it just won't work, clients cannot connect using tls.

Thanks
Alex

The files are in /opt/postal/config/ outside of docker but /config/ inside docker which means you need to have /config/smtp.cert and /config/smtp.key in the config file.

thank you sir.

it seems now that it works but email client reports: The certificate for this server is invalid.

it's a self-signed certificate

You'll either need to import the certificate to the client so it trusts it or re use the certificate from caddy which should be trusted by everyone without much more effort.
