腳本過于簡單，供學(xué)習(xí)和參考。主要了解一下smtplib庫的使用和超時機制的實現(xiàn)。使用signal.alarm實現(xiàn)超時機制。

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

'''

配置文件參考如下：

[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
