使用 IMAP 阅读 gmail 失败

Question

I am running a cron job which executes the python script for reading gmail (2 min interval). I have used imaplib for reading the new mails. This was working fine until yesterday. Suddenly its throwing below error

imaplib.error: [AUTHENTICATIONFAILED] Invalid credentials (Failure)

and sometimes i am getting the below error

raise self.abort(bye[-1]) imaplib.abort: [UNAVAILABLE] Temporary System Error

When i run the same script on a different machine. Its working fine. I am assuming that the host has been blacklisted or something like that.

What are my options ?

I cant generate the Credentials (Gmail API) as this is under company domain account.

Answer 1

try with:

1) https://myaccount.google.com/lesssecureapps?pli=1

2) Gmail Settings -> Forwarding and POP / IMAP -> IMAP Acess to Enable IMAP

Answer 2

Some apps and devices use less secure sign-in technology. So we need to enable Less secure app access option from gmail account.

Steps:

1. Login into Gmail
2. Go to Google Account
3. Navigate to Security section
4. Turn on access for Less secure app access

By following above steps, issue will be resolved.

Answer 3

Got the same error and it was fixed by getting the new google app password. Maybe this will work for someone

Answer 4

This can be solved in two steps:

• Turn on the Less secure app access at: Google Account> Security> Less secure app access
• Enable the IMAP Access at: Gmail Settings> Forwarding and POP / IMAP> IMAP Acess

Answer 5

Thanks guys. Its working now. The issue was that the google blocked our network.. because of multiple attempts. I tried that unlock URL from a different URL and it didnt work. The catch is that, we have to run that URL in the machine where you are trying to run the script. Hope it may help someone :)

Answer 6

Ensure you have entered the right password

Even after that if it is not working

• Enable the IMAP Access at: Gmail Settings> Forwarding and POP / IMAP> IMAP Acess

• Enable 2-factor authentication for the google account

• then generate an app-specific password ( https://myaccount.google.com/apppasswords )

• Use this newly generated password for imap login

Answer 7

Google Gmail - Security - Less secure app access ... won't work anymore !

See https://support.google.com/accounts/answer/6010255?hl=en

“To help keep your account secure, from May 30, 2022, ​​Google no longer supports the use of third-party apps or devices which ask you to sign in to your Google Account using only your username and password.”
