On heroku cloud so don't know

http://nodemailer.com/using-gmail/ Also I checked These link when I enable Less Enable Apps than Email send for some Time than after Fail to send.

                     ` var nodemailer = require('nodemailer');
                      var smtpPool = require('nodemailer-smtp-pool');
                      var transporter = nodemailer.createTransport(smtpPool({
                       service: 'gmail',
                         auth: {
                                  user: '[email protected]',

Gmail does not work well in production with normal authentication. See this post for more information.

[HugoHeneault]

Link broken. :(

[josx]

@higunjan did you solve it?

[shubham-awr]

Try this,
https://accounts.google.com/b/0/DisplayUnlockCaptcha
This will allow machines to access your gmail remotely.

[mateuspontesmoraes]

@shubham-awr tks, problem solved!!!

[oliviercperrier]

I am still having the same problem even with the DisplayUnlockCaptcha...

Do you have any tips??

[J0NNYZER0]

@oliviercperrier - Did you fix this problem?

[JosueCuberoSanchez]

https://accounts.google.com/b/0/DisplayUnlockCaptcha this works.
I received an email by Google that my acccount was being accessed from the server location, if you do just tell Google not to block it.
Those were the steps I took to get it working.

[ninofiliu]

Didn't work for me at first with DisplayUnlockCaptcha, but it worked after I sent a mail immediatly after trying this. I suppose that at first there were issues related to the fact that I have several gmail accounts running on the same browser.

[Codexdrip]

@ninofiliu was correct. Try and close all open gmail accounts except the one you plan to use as the mailer. Navigate to https://accounts.google.com/b/0/DisplayUnlockCaptcha, while that page is open redeploy the app via heroku. You should be good after that.

[c-ywj]

@CRFullStack I had the same issue as OP and I used the link(https://accounts.google.com/b/0/DisplayUnlockCaptcha) with my correct gmail account signed in; redeployed the app to heroku. It was fine for the rest of the day but my nodemailer broke after 2 days. I re-visited: https://accounts.google.com/b/0/DisplayUnlockCaptcha and it was fine again.

Any idea as to why I had to re-enable again? Is there a more permenant solution?

Thanks ver much in advance

@c-ywj did you find any solution?

[dixre-products]

[Abhay304]

Can you explain.. Again?

[Abhay304]

works like magic
thanks @Codexdrip

Locally m getting but through heroku m not.

[higunjan]

@Abhay304 @KowsalyaR97
If locally works and on heroku it won't then please enter the strong password for your Gmail like gU_&#!Gs645.

Also, please check
https://accounts.google.com/b/0/DisplayUnlockCaptcha

Is it enable or not.

For this it is asking me to enable 2 step authentication.
