Requests using smtplib module denied

I have been using the smtplib module in python to send text messages from a gmail account and my requests to connect to the server recently started being denied. My code isn't anything special:

import smtplib
server = smtplib.SMTP( "smtp.gmail.com", 587 )
server.starttls()
server.login( '<gmail_address>', '<gmail_password>’ )
server.sendmail( '<from>', '<number>@mms.att.net', '<msg>’ )

An error is thrown at the 4th line 

raise SMTPAuthenticationError(code, resp)
smtplib.SMTPAuthenticationError: (534,

and gmail notifies me that they have blocked a sign-in attempt from an app, because it didn't meet modern security requirements.

I'm hoping to find a work around that allows me to continue sending SMS messages using the smtplib module.

Solution

  • Google explain that you can lower your security settings but they don't rcommend it, and give precious little in the way of advice apart from that.
