panic from msgwriter if building a mail.Msg from multipart EML #482
Description
Description
I have a case where prepared notifications (EML) are to be sent. Using the EMLToMsgFromString results in a panic: assignment to entry in nil map.
I forked to prepare a fix and saw that it is already fixed with 88f17e1 and the initializing of multiPartBoundary.
To Reproduce
package main
import (
"log"
"github.com/wneessen/go-mail"
)
const eml = `From: <[email protected]>
To: <[email protected]>
Subject: test
Importance: normal
X-Priority: 3
Content-Type: multipart/mixed;
boundary=69529abbd38fadd1d8aea7092ec45071385e19584d9db4a46d5a365a78d1
--69529abbd38fadd1d8aea7092ec45071385e19584d9db4a46d5a365a78d1
Content-Transfer-Encoding: quoted-printable
Content-Type: text/plain; charset=UTF-8

`
func main() {
var (
err error
msg *mail.Msg
)
if msg, err = mail.EMLToMsgFromString(eml); err != nil {
log.Fatal(err)
}
if err = msg.WriteToFile(`msg.eml`); err != nil {
log.Fatal(err)
}
}Expected behaviour
The creation of a file containing EML.
