Describe your problem

Currently, it is not possible to understand why things fail in certain cases. A good example are custom SMTP servers. Figuring out what exactly the parameters are is no easy feat, as there are different security mechanisms (TLS, SMTPS, SMTP without any encryption, ...).

When you have access to the log, that is easy as you'll see error messages like:

{"audience":"application","error":{"message":"tls: first record does not look like a TLS handshake","stack_trace":"stack trace could not be recovered from error type tls.RecordHeaderError"},"file":"/go/pkg/mod/github.com/ory/[email protected]/courier/smtp.go:201","func":"github.com/ory/kratos/courier.(*courier).dispatchEmail","level":"error","message_from":"[email protected]","msg":"Unable to send email using SMTP connection.","service_name":"Ory Kratos","service_version":"master","smtp_server":"smtp.postmarkapp.com:587","smtp_ssl_enabled":true,"time":"2022-07-07T09:47:15Z"}

Describe your ideal solution

It should be possible to see logs related to your project in the console / API.
