Postfix python send mail script configuration

I. Environmental description

We usually need to send mail, for alarm, or email verification requirements, this time the environmental requirements are as follows:

CentOS 6.x minimized installation, installation of Postfix (general system installed with a good mail system), if not please do the following:

#yum Install Postfix-y

Python 2.6+

Ii. introduction of Postfix

Postfix is the Linux platform mail system, installed by default, and automatically boot up to run without too much configuration, but there is a little need to explain, postfix

In the host binding the record domain name will not be treated as spam by default, and the host is not bound to record the domain name, most mail vendors will be considered spam.

Third, Pytho e-mail script

#cat send_mail.py

#!/usr/bin/python#coding:utf-8import smtplib# used to define mail From email.mime.text import mimetext   #邮件发送的内容msg =  "" "    linux Basics      Links: http://pan.baidu.com/s/ 1mhBDhnM "" "#接收人以字符串的形式列出to_str  = " "" [email protected], "" #接收人列表to_list  = to_ Str.replace ("\ n", "").

SMTP (Smtp_server,smtp_port) Server.sendmail (from_user,to_list,mail.as_string ())      #发送人      #接收人列表      #发送的内容server. Quit ()

#python send_mail.py

Open QQ e-mail:

As mentioned in the experiment Postfix host does not have the record domain name resolution binding, so in the QQ mailbox is in the garbage box, and my company Mail did not receive! NetEase Filtered out!

In addition, the above is for the local postfix default SMTP non-SSL sent, but also through the following QQ password authentication to send mail

If you are interested, you can try it.

Smtp_server = "smtp.qq.com" smtp_port = 465server = Smtplib. Smtp_ssl (Smtp_server,smtp_port) server.login (From_user, "Tqnmomfayqpodjdh") Server.sendmail (From_user,to_list, Mail.as_string ())
