email

现有的go-mail实现连接池有一些问题

没有Stat()统计方法
没有最大空闲连接的参数
创建连接之后，没有空闲到一定时间自动关闭的功能，即创建之后一直占着连接资源，即使没有发送邮件的请求

参考go-redis的连接池实现了新的实现

Email for humans

The email package is designed to be simple to use, but flexible enough so as not to be restrictive. The goal is to provide an email interface for humans.

The email package currently supports the following:

From, To, Bcc, and Cc fields
Email addresses in both "test@example.com" and "First Last <test@example.com>" format
Text and HTML Message Body
Attachments
Read Receipts
Custom headers
More to come!

Installation

go get github.com/jordan-wright/email

Note: Version > 1 of this library requires Go v1.5 or above.

If you need compatibility with previous Go versions, you can use the previous package at gopkg.in/jordan-wright/email.v1

Examples

Sending email using Gmail

e := email.NewEmail()
e.From = "Jordan Wright <test@gmail.com>"
e.To = []string{"test@example.com"}
e.Bcc = []string{"test_bcc@example.com"}
e.Cc = []string{"test_cc@example.com"}
e.Subject = "Awesome Subject"
e.Text = []byte("Text Body is, of course, supported!")
e.HTML = []byte("<h1>Fancy HTML is supported, too!</h1>")
e.Send("smtp.gmail.com:587", smtp.PlainAuth("", "test@gmail.com", "password123", "smtp.gmail.com"))

Another Method for Creating an Email

You can also create an email directly by creating a struct as follows:

e := &email.Email {
	To: []string{"test@example.com"},
	From: "Jordan Wright <test@gmail.com>",
	Subject: "Awesome Subject",
	Text: []byte("Text Body is, of course, supported!"),
	HTML: []byte("<h1>Fancy HTML is supported, too!</h1>"),
	Headers: textproto.MIMEHeader{},
}

Creating an Email From an io.Reader

You can also create an email from any type that implements the io.Reader interface by using email.NewEmailFromReader.

Attaching a File

e := NewEmail()
e.AttachFile("test.txt")

A Pool of Reusable Connections

(var ch <-chan *email.Email)
p := email.NewPool(
	"smtp.gmail.com:587",
	4,
	smtp.PlainAuth("", "test@gmail.com", "password123", "smtp.gmail.com"),
)
for i := 0; i < 4; i++ {
	go func() {
		for e := range ch {
			p.Send(e, 10 * time.Second)
		}
	}()
}
