Mail.go

mail.go is a Go package for working with email. It provides a simple and efficient way to send and receive emails using the SMTP protocol.

Here are some of the key features of the mail package:

1. Sending emails: The mail package allows you to send emails using the SMTP protocol. You can specify the sender, recipient, subject, and body of the email.
2. Receiving emails: The package also provides support for receiving emails using the POP3 and IMAP protocols.
3. Email parsing: The mail package includes a parser for parsing email messages, which allows you to extract information such as the sender, recipient, subject, and body of the email.
4. Email formatting: The package also includes a formatter for formatting email messages, which allows you to create well-formatted email messages.

Here is an example of how you might use the mail package to send an email:

package main

import (
    "fmt"
    "log"

    "github.com/jordan-wright/mail"
)

func main() {
    // Create a new email message
    msg := mail.NewMessage()
    msg.SetHeader("From", "[email protected]")
    msg.SetHeader("To", "[email protected]")
    msg.SetHeader("Subject", "Hello, world!")
    msg.SetBody("Hello, world!", "text/plain")

    // Create a new SMTP client
    client := mail.NewSMTPClient("smtp.example.com", 587)
    client.SetAuth("username", "password")

    // Send the email
    err := client.Send(msg)
    if err!= nil {
        log.Fatal(err)
    }

    fmt.Println("Email sent successfully!")
}

This code creates a new email message with a sender, recipient, subject, and body, and then sends it using an SMTP client.

The mail package is a useful tool for working with email in Go, and it can be used for a variety of tasks such as sending automated emails, parsing email messages, and more.
