Unable to Configure Email Sending Without `WithSSLPort` Using YAML Configuration #427

I'm having trouble configuring the email sending functionality in Uptrace (from docker) following the documentation at Sending Emails and based on the guidance in Issue #379.

I've written a working Go sample using the go-mail package that successfully sends an email through Gmail. The key to getting it working is not using the mail.WithSSLPort option. Here’s the relevant code that works for my setup:

package main                                                                                                                                                                                                                                                                                                       

import (
        "fmt"
        "log"

        mail "github.com/wneessen/go-mail"
)

func main() {
        from := "example@gmail.com"
        options := []mail.Option{
                mail.WithSMTPAuth("PLAIN"),
                mail.WithUsername("example@gmail.com"),
                mail.WithPassword("password_example"),
                mail.WithTLSPortPolicy(mail.TLSMandatory),
                // mail.WithSSLPort(false), // Error: dial failed: tls: first record does not look like a TLS handshake
                // mail.WithSSLPort(true), // Error: dial failed: tls: first record does not look like a TLS handshake
                // <no WithSSLPort>, // Success
                mail.WithPort(587),
        }

        // Create a new mailer instance
        client, err := mail.NewClient("smtp.gmail.com", options...)
        if err != nil {
                fmt.Println(err)
                return
        }

        // Create a new message
        msg := mail.NewMsg()
        msg.Subject("test")
        msg.SetBodyString(mail.TypeTextHTML, "test")
        if err := msg.FromFormat(from, from); err != nil {
                fmt.Println(err)
                return
        }
        if err := msg.To(from); err != nil {
                fmt.Println(err)
                return
        }

        // Send the email
        if err := client.DialAndSend(msg); err != nil {
                log.Fatal(err)
        }

        log.Println("Email sent successfully!")
}

The key point is that the email is sent only when mail.WithSSLPort is not called. However, I can't figure out how to replicate this behavior using the YAML configuration in Uptrace.

The current Go code in pkg/bunapp/app.go always calls mail.WithSSLPort due to the switch logic, making it difficult to bypass this option. Here is the relevant code:

options := []mail.Option{
    mail.WithSMTPAuth(cfg.AuthType),
    mail.WithUsername(cfg.Username),
    mail.WithPassword(cfg.Password),
}

switch {
case cfg.TLS == nil:
    options = append(options,
        mail.WithTLSPortPolicy(mail.TLSOpportunistic),
        mail.WithSSLPort(false), // Always called
        mail.WithPort(cfg.Port),
    )
case cfg.TLS.Disabled:
    options = append(options,
        mail.WithTLSPortPolicy(mail.NoTLS),
        mail.WithPort(cfg.Port),
    )
default:
    options = append(options,
        mail.WithTLSPortPolicy(mail.TLSMandatory),
        mail.WithSSLPort(false), // Always called
        mail.WithPort(cfg.Port),
    )

    tlsCfg, err := cfg.TLS.TLSConfig()
    if err != nil {
        return nil, err
    }
    options = append(options, mail.WithTLSConfig(tlsCfg))
}

My question is: how can I configure the YAML to avoid using mail.WithSSLPort and successfully send emails, just like in the working Go sample?

Any guidance on how to bypass or modify the switch logic in app.go or structure the configuration to disable WithSSLPort would be greatly appreciated.
