email - 使用 luasocket smtp 和 ssl 发送电子邮件

Question

我一直在尝试使用帖子中描述的代码发送电子邮件:

lua send mail with gmail account

代码由Michal Kottman重复如下:

-- Michal Kottman, 2011, public domain
local socket = require 'socket'
local smtp = require 'socket.smtp'
local ssl = require 'ssl'
local https = require 'ssl.https'
local ltn12 = require 'ltn12'

function sslCreate()
    local sock = socket.tcp()
    return setmetatable({
        connect = function(_, host, port)
            local r, e = sock:connect(host, port)
            if not r then return r, e end
            sock = ssl.wrap(sock, {mode='client', protocol='tlsv1'})
            return sock:dohandshake()
        end
    }, {
        __index = function(t,n)
            return function(_, ...)
                return sock[n](sock, ...)
            end
        end
    })
end

function sendMessage(subject, body)
    local msg = {
        headers = {
            to = 'Your Target <target email>',
            subject = subject
        },
        body = body
    }

    local ok, err = smtp.send {
        from = '<your email>',
        rcpt = '<target email>',
        source = smtp.message(msg),
        user = 'username',
        password = 'password',
        server = 'smtp.gmail.com',
        port = 465,
        create = sslCreate
    }
    if not ok then
        print("Mail send failed", err) -- better error handling required
    end
end

如果我从 gmail 发送邮件，该代码可以正常工作。但是，当我使用 smtpout.secureserver.net(同一端口)的 godaddy smtp 服务器时，它无法发送消息。我刚收到错误代码 550。 请任何人帮助我弄清楚如何进行这项工作。

谢谢。

感谢这篇文章，它成功了:

Trying to send email to Google through in Python, email being denied

我只是更改了代码以在标题表中添加 from 字段，如下所示:

-- Michal Kottman, 2011, public domain
local socket = require 'socket'
local smtp = require 'socket.smtp'
local ssl = require 'ssl'
local https = require 'ssl.https'
local ltn12 = require 'ltn12'

function sslCreate()
    local sock = socket.tcp()
    return setmetatable({
        connect = function(_, host, port)
            local r, e = sock:connect(host, port)
            if not r then return r, e end
            sock = ssl.wrap(sock, {mode='client', protocol='tlsv1'})
            return sock:dohandshake()
        end
    }, {
        __index = function(t,n)
            return function(_, ...)
                return sock[n](sock, ...)
            end
        end
    })
end

function sendMessage(subject, body)
    local msg = {
        headers = {
            from = "<your email>",
            to = 'Your Target <target email>',
            subject = subject
        },
        body = body
    }

    local ok, err = smtp.send {
        from = '<your email>',
        rcpt = '<target email>',
        source = smtp.message(msg),
        user = 'username',
        password = 'password',
        server = 'smtp.gmail.com',
        port = 465,
        create = sslCreate
    }
    if not ok then
        print("Mail send failed", err) -- better error handling required
    end
end
