# quotedprintable
## Introduction
Package quotedprintable implements quoted-printable and message header encoding
as specified by RFC 2045 and RFC 2047.
It is a copy of the Go 1.5 package `mime/quotedprintable`. It also includes
the new functions of package `mime` concerning RFC 2047.
This code has minor changes with the standard library code in order to work
with Go 1.0 and newer.

# Change Log
All notable changes to this project will be documented in this file.
This project adheres to [Semantic Versioning](http://semver.org/).
## [2.0.0] - 2015-09-02
- Mailer has been removed. It has been replaced by Dialer and Sender.
- `File` type and the `CreateFile` and `OpenFile` functions have been removed.
- `Message.Attach` and `Message.Embed` have a new signature.
- `Message.GetBodyWriter` has been removed. Use `Message.AddAlternativeWriter`
instead.
- `Message.Export` has been removed. `Message.WriteTo` can be used instead.
- `Message.DelHeader` has been removed.
- The `Bcc` header field is no longer sent. It is far more simpler and
efficient: the same message is sent to all recipients instead of sending a
different email to each Bcc address.
- LoginAuth has been removed. `NewPlainDialer` now implements the LOGIN
authentication mechanism when needed.
- Go 1.2 is now required instead of Go 1.3. No external dependency are used when
using Go 1.5.

Thank you for contributing to Gomail! Here are a few guidelines:
## Bugs
If you think you found a bug, create an issue and supply the minimum amount
of code triggering the bug so it can be reproduced.
## Fixing a bug
If you want to fix a bug, you can send a pull request. It should contains a
new test or update an existing one to cover that bug.
## New feature proposal
If you think Gomail lacks a feature, you can open an issue or send a pull
request. I want to keep Gomail code and API as simple as possible so please
describe your needs so we can discuss whether this feature should be added to
Gomail or not.

# Gomail
[![Build Status](https://travis-ci.org/go-gomail/gomail.svg?branch=v2)](https://travis-ci.org/go-gomail/gomail) [![Code Coverage](http://gocover.io/_badge/gopkg.in/gomail.v2)](http://gocover.io/gopkg.in/gomail.v2) [![Documentation](https://godoc.org/gopkg.in/gomail.v2?status.svg)](https://godoc.org/gopkg.in/gomail.v2)
## Introduction
Gomail is a simple and efficient package to send emails. It is well tested and
documented.
Gomail can only send emails using an SMTP server. But the API is flexible and it
is easy to implement other methods for sending emails using a local Postfix, an
API, etc.
It is versioned using [gopkg.in](https://gopkg.in) so I promise
there will never be backward incompatible changes within each version.
It requires Go 1.2 or newer. With Go 1.5, no external dependencies are used.
## Features
Gomail supports:
- Attachments
- Embedded images
- HTML and text templates
- Automatic encoding of special characters
- SSL and TLS
- Sending multiple emails with the same SMTP connection
## Documentation
https://godoc.org/gopkg.in/gomail.v2
## Download
go get gopkg.in/gomail.v2
## Examples
See the [examples in the documentation](https://godoc.org/gopkg.in/gomail.v2#example-package).
## FAQ
### x509: certificate signed by unknown authority
If you get this error it means the certificate used by the SMTP server is not
considered valid by the client running Gomail. As a quick workaround you can
bypass the verification of the server's certificate chain and host name by using
`SetTLSConfig`:
package main
import (
"crypto/tls"
"gopkg.in/gomail.v2"
)
func main() {
d := gomail.NewDialer("smtp.example.com", 587, "user", "123456")
d.TLSConfig = &tls.Config{InsecureSkipVerify: true}
// Send emails using d.
}
Note, however, that this is insecure and should not be used in production.
