利用python发送邮件_利用python实现简单的邮件发送客户端示例

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 = ******@

password = ******

smtp_server =

[qq]

from_addr = ******@

password = ******

smtp_server =
