I am working on deploying my Node.js app. However I am having issues with having the registration email getting sent out.
const transporter = nodemailer.createTransport({
service: 'Gmail',
auth: {
user: GMAIL_USER,
pass: GMAIL_PASS,
},
});
......
......
transporter.sendMail({
to: newUser.email,
subject: 'Confirm Email',
html: `Please click this email to confirm your email: ${url}`
});
This works perfectly when I try running it on local host, but as soon as I upload the files to my server and try it, google blocks the sign in attempt, and I get an email saying
Someone just used your password to try to sign in to your account. Google blocked them, but you should check what happened.
Every time, I click the button "this was me", but any future attempts still get blocked.
I have "less secure apps" enabled. Is there a way to whitelist an IP to send from my gmail? or a way to get this working in general?
You have two options.Either you set the access to less secure apps setting to Enabled or you obtain an accessToken and a refreshToken from Google OAuth2.0 and use them in your nodemailer config
For option one go to https://www.google.com/settings/security/lesssecureapps
For option two go to https://console.developers.google.com/apis/credentials
if you choose option two your config for the transport will look something like this:
auth: {
type: 'OAuth2',
user: 'user#example.com',
accessToken: 'ya29.Xx_XX0xxxxx-xX0X0XxXXxXxXXXxX0x'
}
Sometimes people who don't assign recovery email, phone number .In that scenario also google hinders login. In my case google first allowed me on turning less secure app but very next day it denied. So I added recovery email for that particular email and it worked. So that's how I think google security algo works.
Had to fill out some hidden captcha for gmail, then everything worked fine. Sadly dont have the link, or id post it.
I'm creating a Twitter bot and I'm implementing a method that sends me a email if there is an error. As I'm already using the google API to access Google Drive (have no problem here), I decided to use the service account to send the email (Google console says it could be used that way)
The method I've come up to send the email so far is:
var config = require('./config/mail');
var google = require('./config/google');
var nodemailer = require('nodemailer');
var send = function (args) {
let transporter = nodemailer.createTransport({
'service': 'gmail',
'auth': {
'type': 'OAuth2',
'user': google.client_email,
'serviceClient': google.client_id,
'privateKey': google.private_key
}
});
transporter.on('token', token => console.log(token));
let message = {
'from': `"${config.serverFromName}" <${config.serverFromMail}>`,
'to': args.to,
'subject': args.subject,
'text': args.text,
'html': `<p>${args.text}</p>`
};
transporter.sendMail(message, (err, info) => {
if (err) {
console.log('Mail couldn\'t be sent because: ' + err);
} else {
console.log('Mail sent');
}
});
};
The config/google file contains the data that Google generates for you when you create a service account. config.serverFromName and config.serverFromMail are the name and email of the sender (not the same as the service account id). args contains the recipent email and the content
When I test the send method, I got the following message in my console:
Mail couldn't be sent because: Error: Invalid login: 535-5.7.8 Username and Password not accepted. Learn more at
535 5.7.8 https://support.google.com/mail/?p=BadCredentials z123sm543690vkd.10 - gsmtp
I know the token is being created correctly because the listener I created is printing it:
{ user: 'name#project.iam.gserviceaccount.com',
accessToken: 'ya29.ElmIBLxzfU_kkuZeyISeuRBeljmAe7HNTlwuG4K12ysUNo46s-eJ8NkMYHQqD_JrqTlH3yheNc2Aopu9B5vw-ivEqvPR4sTDpWBOg3xUU_4XiJEBLno8FHsg',
expires: 1500151434603 }
Searching on the Internet I found that it may be a problem with the OAuth scope. However, all the info that talks about it refers to using Client IDs, not service accounts. I don't find that option in the Google developer console, either.
Any ideas of what I'm doing wrong?
Bottom Line: The specific way Google describes a service account is INCOMPATIBLE with nodemailer. BUT there is a way!
I have just spent countless hours myself up over this same issue! I have come to the conclusion, Google's Admin Console has removed half this capability indirectly. The console does not provide a way to authorize (a user accepting the consent screen) the desired scope the very first time with a service account.
First up, follow the Node.JS Quickstart instructions for Google Drive API to authorize a scope and receive a refresh token.
Go to console.developers.google.com, build a OAuth2.0 Client Id, and download the client_secret.json file.
Create a separate temporary module folder and use NPM to download google api modules
npm install googleapis
npm install google-auth-library
Create a quickstart.js file
Place your client_secret.json file next to quickstart.js
Line 7 in the quickstart.js is the array to define the scopes you intend to allow the application to access. Modify it as you see necessary. It is highly recommended to only provision access for what is intended. See Gmail API Scopes.
RUN node quickstart.js
Open the URL in a browser, authenticate, and copy the code from the browser back into the terminal window. This will download a nodejs-gmail-quickstart.json file which the location will be provided in stdout.
This is the part you are unable to accomplish for a Service Account. This action authorizes the scopes provided in the SCOPES array to the downloaded access_token & refresh token.
NOTE: access_token's have a lifespan of 1 hour. refresh_token's are immortal.
Now you have an authorized refresh_token!
Next is setting up your auth object with 3LO in Nodemailer. I would look more at the bottom examples because not all values are required. My auth looks like this:
const mailbot = nodemailer.createTransport({
host: 'smtp.gmail.com',
port: 587, // TLS (google requires this port for TLS)
secure: false, // Not SSL
requireTLS: true, // Uses STARTTLS command (nodemailer-ism)
auth: {
// **HIGHLY RECOMMEND** ALL values be
// read in from a file not placed directly in code.
// Make sure that file is locked down to only the server daemon
type : 'OAuth2',
user : config.client_email,
scope : "https://www.googleapis.com/auth/gmail.send",
clientId : config.client_id,
clientSecret: secret,
refreshToken: activeToken.refresh_token
// AT RUNTIME, it looks like this:
//type : 'OAuth2',
//user : 'user#gmail.com', // actual user being impersonated
//scope : "", //Optional, but recommend to define for the action intended
//clientId : '888888888998-9xx9x99xx9x99xx9xxxx9xx9xx9x88x8xxx.apps.googleusercontent.com',
//clientSecret: 'XxxxxXXxX0xxxxxxxx0XXxX0',
//refreshToken: '1/XXxXxsss-xxxXXXXXxXxx0XXXxxXXx0x00xxx'
}
});
TIP: Gmail will rewrite the FROM field from any email sent with the authorized user account (user impersonated). If you want to customize this slightly, use the syntax { FROM: '"Display NAME" <user email>' } and it will not overwrite your display name choice since the email matches.
NOTE: nodemailer will make a token request out to https://accounts.google.com/o/oauth2/token with the refresh token to automatically obtain an access_token.
Unfortunately, nodemailer lacks the functionality to save a received token out to a file directly but instead just uses this.emit(). If the server stays active it will not be an issue but as mine is only bursting, it will always incur a delay as a new access_token will be requested every time.
[SECURITY] Hopefully this works for you! It is disappointing to loose the private key encryption a service account with 2LO would bring but at least this Client ID way is very hard to spoof. I was concerned about security but reading more I am okay with this implementation. See Google Identity Platform (Nodemailer uses the HTTP/REST details) and given
[1] Google's OAuth 2.0 endpoint is at
https://accounts.google.com/o/oauth2/v2/auth. This endpoint is
accessible only over HTTPS. Plain HTTP connections are refused.
[5] After the web server receives the authorization code, it can exchange
the authorization code for an access token.
you are using TLS to connect initially for an authorization code, then matching it with your client ID data, and a refresh_token (you must go through the hassle we did above) then you can receive an access_token to actually interact with Google APIs.
As long as you increase your security posture with keeping the OAuth2.0 Client ID (highly random username), secret, and refresh token as separate, secure, and hidden as much as possible, you should be able to sleep soundly. GOOD LUCK!
After visiting the OAuth 2.0 Playground and experimenting with all possible variations of gmail-related sub-scopes, even selecting them altogether...
https://www.googleapis.com/auth/gmail.labels
https://www.googleapis.com/auth/gmail.send
https://www.googleapis.com/auth/gmail.readonly
https://www.googleapis.com/auth/gmail.compose
https://www.googleapis.com/auth/gmail.insert
https://www.googleapis.com/auth/gmail.modify
https://www.googleapis.com/auth/gmail.metadata
https://www.googleapis.com/auth/gmail.settings.basic
https://www.googleapis.com/auth/gmail.settings.sharing
...the error message described in the OP title still persist:
Error: Invalid login: 535-5.7.8 Username and Password not accepted
It seems that NodeMailer is not capable of connecting via the scopes mentioned above. In fact, it explicitly mentions in the "Troubleshooting" section of its OAuth2 SMTP transport docs
The correct OAuth2 scope for Gmail SMTP is https://mail.google.com/, make sure your client has this scope set when requesting permissions for an user
Although this gives access to more than just sending emails, it works!
The only alternative to reach a more fine grained scope solution seems to be to resort to google's own Gmail API, where you can pass scopes when generating the OAuth2 client (which should of course at least include the scopes granted at the time the OAuth consent screen was shown):
oAuth2Client.generateAuthUrl({
access_type: 'offline',
scope: SCOPES,
})
I was able to get service accounts working with Google & nodemailer:
these were the steps:
Log in to console.- https://console.cloud.google.com/
Create a service account under the project.
Click on the new service account, go to permissions and add a member. You will use this member's email address when sending the request.
Create keys for the service account. - keys -> add key. https://console.cloud.google.com/iam-admin/serviceaccounts
Download your key file. You will get something like service-account-name-accountid.json. It will have all the information you need to get the code below running.
Delegate authority to your service account https://developers.google.com/identity/protocols/oauth2/service-account#delegatingauthority. Addhttps://mail.google.com/ as the scope.
Write some code like below:
const nodemailer = require('nodemailer');
const json = require('./service-account-name-accountid.json');
const sendEmail = async (email, subject, text) => {
try {
const transporter = nodemailer.createTransport({
host: 'smtp.gmail.com',
port: 465,
secure: true,
auth: {
type: 'OAuth2',
user: email, //your permissioned service account member e-mail address
serviceClient: json.client_id,
privateKey: json.private_key
}
});
await transporter.verify();
await transporter.sendMail({
from: json.service_email,
to: email, //you can change this to any other e-mail address and it should work!
subject,
text
});
console.log('success!');
return {
status : 200
}
} catch (error) {
console.log(error);
return {
status : 500,
error
}
}
}
sendEmail('your_permissioned_service_account_email_address#some_place.com, 'testing 123', 'woohoo!');
I am trying to send email to my other email from amazon SES verified email, but the programs gives an error that email address in to field is not verified. I am making a web app which allows user to log in using AWS Cognito so I dont have their email addresses in database. I need to send email to them on an event(I cannot use SNS because I need to send emails to selective persons which I have figured out.) So my questions are:
a)Do we need to verify SES email of the recipient also?
b)If yes, how can we use the cognito identity pool to verify their email addresses for SES.
code:
var aws = require("aws-sdk");
aws.config.update({
region: "us-west-2",
});
var ses = new aws.SES({"accessKeyId": "Mykey", "secretAccessKey":"YY","region":"us-west-2"})
var to = ['xyz#gmail.com']
var from='abc#gmail.com'
ses.sendEmail( {
Source: from,
Destination: { ToAddresses: to },
Message: {
Subject:{
Data:"Sending emails through SES"
},
Body: {
Text: {
Data: 'Stop your messing around',
}
}
}
}
, function(err, data) {
if(err) throw err
console.log('Email sent:');
console.log(data);
}
Error:
MessageRejected: Email address is not verified. The following identities failed the check in region US-WEST-2: xyz#gmail.com
If you're testing this inside your SES sandbox, you need to manually verify the recipient email addresses before it will allow you to send.
This step isn't required after leaving the sandbox, but it's a reasonable default safety setting when testing email-related functionality during development and not wanting bogus emails to go our for real.
Amazon SES Email Sending Errors (relevant portion in bold):
Email address is not verified. The following identities failed the
check in region : , , —You
are trying to send email from an email address or domain that you have
not verified with Amazon SES. This error could apply to the "From",
"Source", "Sender", or "Return-Path" address. If your account is still
in the sandbox, you also must verify every recipient email address
An easier way to test your email sending in AWS without needing to send actual emails would be to use their mailbox simulator:
The Amazon SES mailbox simulator is a set of test email addresses.
Each email address represents a specific scenario. You can send emails
to the mailbox simulator when you want to:
Test your application without having to create test "To" addresses.
My Kaaproject Cloud service deployed over MS Azure is unable to send any email request, which is shunning me from creating tenants.
My Outgoing SMTP mail server details are:
From Address: admin#kaaproject.org
SMTP Protocol: SMTP
SMTP Host:
SMTP Port: 25
SMTP Timeout: 10000
Username: New Username
Password: New Password
Whenever I try to create a user under Tenant, it provides me with this error:
Unexpected service error occurred: Failed to send email with temporary password. Please, check outgoing email settings. See server logs for details.
Check your outgoing mail settings. Also, investigate Kaa server logs for more details. See troubleshooting guide.
I use nodemailer to send email to my users, previously I used gmail and it work just fine, but now, Im my custom email which provided by gmail
admin#example.io
Heres the code
var transporter = nodemailer.createTransport(smtpTransport({
host : 'smtp.gmail.com',
secureConnection : true,
auth : {
user: 'admin#example.io',
pass: 'pass'
}
}));
Since my custom account is from gmail, I expect the host to be stmp.gmail.com, but it shows this error
{ [Error: Invalid login:]}
Im not sure what is the problem over here.
GoogleApps use the same smtp server.
Make sure your google apps administrator doesn't block SMTP relay service.
