from_name = '刘白菜'
from_mail = 'liubaicai@163.com'
#Servers and Authentication
smtp_host = 'smtp.163.com'
smtp_port = 25
smtp_domain = '163.com'

#The subject and the message
#The date/time should look something like: Thu, 03 Jan 2006 12:33:22 -0700
t = Time.now
msg_date = t.strftime("%a, %d %b %Y %H:%M:%S +0800")
#Compose the message for the email
msg = <<END_OF_MESSAGE
Date: #{msg_date}
From: #{from_name} <#{from_mail}>

#{msg_body}
END_OF_MESSAGE
Net::SMTP.start(smtp_host, smtp_port, smtp_domain, smtp_user, smtp_pwd, :plain) do |smtp|

Email.new.send('liubaicai@qq.com','Sending 邮件','测试测试')
发送带附件的邮件的方法：
require 'net/smtp'
filename = "/tmp/test.txt"
# 读取文件并编码为base64格式
filecontent = File.read(filename)
encodedcontent = [filecontent].pack("m") # base64
marker = "AUNIQUEMARKER"
body =<<EOF

mailtext = part1 + part2 + part3
# 发送邮件
begin
Net::SMTP.start('localhost') do |smtp|
smtp.sendmail(mailtext, 'me@fromdomain.net',
['test@todmain.com'])
