脚本过于简单，供学习和参考。主要了解一下smtplib库的使用和超时机制的实现。使用signal.alarm实现超时机制。

example:
from emailtest import emailtest
eb = emailtest.EmailObject("******@******.com","test content")
eb.send_email()
tips:
increase timeout:
eb.timeout = 10
increase retry times:
eb.retry = 5
'''
配置文件参考如下：
[default]
from_addr = ******@******.com
password = ******
smtp_server = smtp.******.com
[163]
from_addr = ******@163.com
password = ******
smtp_server = smtp.163.com
[qq]
from_addr = ******@qq.com
password = ******
smtp_server = smtp.qq.com
以上这篇利用python实现简单的邮件发送客户端示例就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持移动技术网。
