Simple wrapper around luasoket smtp.send

lua-sendmail

Simple wrapper around luasoket smtp.send.
See documentation.

Usage

local sendmail = require "sendmail"
local from, to, server = '[e-mail]', '[e-mail]', '127.0.0.1'

sendmail(from, to, server, {"Subject", [[
  This is mail body.
]],
  file = {
    name = 'message.txt';
    data = 'file content';
  };
})

Send mail with SSL/TLS connection (using LuaSec)

sendmail{
  server = {
    ssl = {
      protocol = "sslv3",
      verify   = {"peer", "fail_if_no_peer_cert"},
      options  = {"all", "no_sslv2"},
    },
    address  = ...;
    user     = ...;
    password = ...;
  },
  ...
}

Send mail with SSL/TLS connection (using custom SSL connection)

-- I use lua-lluv-ssl library.
local ut     = require "lluv.utils"
local ssl    = require "lluv.ssl"
local socket = require "lluv.ssl.luasocket"

-- this is asyncronus call
ut.corun(sendmail, {
  server = {
    ssl = ssl.context{
      protocol = "sslv3",
      verify   = {"peer", "fail_if_no_peer_cert"},
      options  = {"all", "no_sslv2"},
    },
    create = socket.ssl;
    address  = ...;
    user     = ...;
    password = ...;
  },
  ...
})

Send attached files as single zip archive

local ZipWriter = require "ZipWriter"

sendmail{
  ...
  message = {
    ...
    file = {
      source = ZipWriter.source(ZipWriter.new(), {
        {"file01.txt", "path/to/file01.txt"},
        {"file02.txt", "path/to/file02.txt"},
      }),
      name = 'files.zip';
    }
  }
}

Dependences

• LuaSocket
• LuaSec - to support SMTPS protocol
• Lua-cURL - can be used to handle SMTP(S) protocol and IO. Still require LuaSocket to build message itself
