Could you try this SendMail function (using gomail.SetSendMail(sendMail))
and tell me if it works when the certificate is invalid?
func sendMail(addr string, a smtp.Auth, from string, to []string, msg
[]byte) error {
c, err := smtp.Dial(addr)
if err != nil {
return err
}
defer c.Close()
if ok, _ := c.Extension("STARTTLS"); ok {
host, _, _ := net.SplitHostPort(addr)
config := &tls.Config{ServerName: host, InsecureSkipVerify: true}
if err = c.StartTLS(config); err != nil {
return err
}
}
if a != nil {
if ok, _ := c.Extension("AUTH"); ok {
if err = c.Auth(a); err != nil {
return err
}
}
}
if err = c.Mail(from); err != nil {
return err
}
for _, addr := range to {
if err = c.Rcpt(addr); err != nil {
return err
}
}
w, err := c.Data()
if err != nil {
return err
}
_, err = w.Write(msg)
if err != nil {
return err
}
err = w.Close()
if err != nil {
return err
}
return c.Quit()
}

copy the send function from smtp to my own package, but I gave up since it
relied on to much package stuff.
The issue is that TLS in the golang smtp package always attempts smtp, if
the server announces it. If it fails (we have an expired certificate in our
case), the client fails, and doesn't attempt a non-TLS connection.
See
http://golang.org/src/pkg/net/smtp/smtp.go?s=1593:1652#L282 for the
offending code path.
So yes - if you could make TLS optional that would be great.

PS. Thanks for the nice package, it has been very easy to use!

Could you provide a send function where the tls config is exposed so
that one is able to set the InsecureSkipVerify flag for StartTLS ?
Thanks,

Hello, I wrote a new package: gomail. It provides a simple interface to
easily write and send emails. It supports attachments, multipart emails and
encoding of non-ASCII characters.
Documentation:
http://godoc.org/github.com/alexcesaro/mail/gomailSource code:
https://github.com/alexcesaro/mail/Here is an example:
package main
import (
"log"
"github.com/alexcesaro/mail/gomail"
)
func main() {
msg := gomail.NewMessage()
msg.SetAddressHeader("From", "al...@example.com", "Alex")
msg.SetHeader("To", "b...@example.com")
msg.AddHeader("To", "co...@example.com")
msg.SetHeader("Subject", "Hello!")
msg.SetBody("text/plain", "Hello Bob and Cora!")
msg.AddAlternative("text/html", "Hello <b>Bob</b> and
<i>Cora</i>!")
if err := msg.Attach("/home/Alex/lolcat.jpg"); err != nil {
log.Println(err)
return
}
m := gomail.NewMailer("smtp.example.com", "user", "123456", 25)
if err := m.Send(msg); err != nil { // This will send the email
to Bob and Cora
log.Println(err)
}
}
Hope you will enjoy it! Feedback is welcome!
