TLS with selfsigned certificate

Question

I\'m trying to establish a TLS connection with the use of a self signed server certificate.

I generated the certificate with this example code: http://golang.org/src

You need to use the InsecureSkipVerify flag, refer to https://groups.google.com/forum/#!topic/golang-nuts/c9zEiH6ixyw.

The related code of this post (incase the page is offline):

smtpbox := "mail.foo.com:25"
c, err := smtp.Dial(smtpbox)

host, _, _ := net.SplitHostPort(smtpbox)
tlc := &tls.Config{
    InsecureSkipVerify: true,
    ServerName:         host,
}
if err = c.StartTLS(tlc); err != nil {
    fmt.Printf(err)
    os.Exit(1)
} 
// carry on with rest of smtp transaction 
// c.Auth, c.Mail, c.Rcpt, c.Data, etc
