Python3 implement 126 mailbox 163 mailbox SMTP Send mail

e-mail to remind the role, when the crawler encountered an exception or the server encountered problems, you can report to yourself in a timely manner by email.
The protocol for sending mail is Stmp,python built-in support for SMTP, which can send plain text messages, HTML messages, and messages with attachments.

SMTP protocol

First understand SMTP (Simple Mail Transfer Protocol), the mail delivery Agent uses the SMTP protocol to send email to the recipient's mail server. The SMTP protocol can only be used to send messages, not to receive messages, and most mail-sending servers use the SMTP protocol. The default TCP port number for the SMTP protocol is 25.

Configuration before sending the message:

It says that the mail is sent using the SMTP protocol, so you need to check whether your sender's mailbox has an SMTP protocol enabled, if not, it needs to be turned on, I test using a 163.com mailbox as the sender's mailbox, the SMTP protocol is turned on in the settings as shown in.

Construct a simple plain text message

From Email.mime.text import Mimetext
msg = mimetext (' Python crawler run exception, exception information for encountering HTTP 403 ', ' plain ', ' utf-8 ')
Three parameters required to construct a Mimetext object
Message body, ' Python crawler running exception, exception information for encountering HTTP 403 '
Mimel's subtype, ' plain ' represents plain text
encoded format, ' Utf-8 '
