go-smtpsrv's Introduction

A SMTP Server Package

a simple smtp server library for writing email servers like a boss.

Quick Start

go get github.com/alash3al/go-smtpsrv

package main

import (
	"fmt"

	"github.com/alash3al/go-smtpsrv/v3"
)

func main() {
	handler := func(c smtpsrv.Context) error {
		// ...
		return nil
	}

	cfg := smtpsrv.ServerConfig{
		BannerDomain:  "mail.my.server",
		ListenAddr: ":25025",
		MaxMessageBytes: 5 * 1024,
		Handler:     handler,
	}

	fmt.Println(smtpsrv.ListenAndServe(&cfg))
}

SPF validation is wrong

Hey
the SPF validation does not work. And I think it's broken for everyone if I see it correctly. This is the code:

go-smtpsrv/context.go

Lines 60 to 66 in d1b581b

 func (c Context) SPF() (SPFResult, string, error) { 

 _, host, err := SplitAddress(c.From().Address) 

 if err != nil { 

 return spf.None, "", err 

 } 

 return spf.CheckHost(net.ParseIP(c.RemoteAddr().String()), host, c.From().Address)

The problem is that c.RemoteAddr() contains also the port (1.2.3.4:32152) and so net.ParseIP will fail and return nil. This is what happens at least in my case.

DKIM

Hi @alash3al

Is it possible to add DKIM checks?

I think this framework will work: https://github.com/redsift/dkim

354 End data with <CR><LF>.<CR><LF> is broken

Using logrus_mail to send email via smtpsrv results in "503 Bad sequence of commands".

Verified manually:

Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 localhost ESMTP
EHLO localhost
250-Greets localhost
250-PIPELINING

RAW Message

hello @alash3al

How can I get the RAW message?

Example to Send EMAIL

Can you tell How I can use this for Sending Emails?

Charset issue with Windows-1252 (and other ones ?)

As I explained here : alash3al/smtp2http#14

There is an issue with ioutil.ReadAll reading bytes of some mail contents in french mails with accents.

It should be better to detect charset in Content-Type and correctly decode with charmap for example.

I m not used in Go programming. I don't think I'm gonna be able to help you fixing this.
