从 Rails 应用程序发送电子邮件时发生错误(在暂存环境中)

我从我的 Rails 应用程序发送电子邮件。它在开发环境中工作得很好，但是在分段上失败了。我得到以下错误:

Net::SMTPAuthenticationError (534-5.7.14 <https://accounts.google.com/ContinueSignIn?plt=AKgnsbtdF0yjrQccTO2D_6)

请注意，我的 I 没有一个域名为我的阶段。

下面是 staging.rb 中的设置

config.action_mailer.delivery_method = :smtp
config.action_mailer.default_url_options = { :host => "my.ip.addr.here:80" }
config.action_mailer.smtp_settings = {
:address => "smtp.gmail.com",
:port => 587,
:domain => 'my.ip.addr.here:80'
:user_name => "my_email_name@gmail.com",
:password => "my_email_password",
:authentication => 'login'
}

求你了，救命。

剪辑。

在添加 :tls => true选项后，我得到

OpenSSL::SSL::SSLError (Unrecognized SSL message, plaintext connection?)

然后我把端口改为25，现在我得到了这个(延迟30秒) :

Timeout::Error (execution expired)

Solved! I simply changed password for my gmail account and somehow errors disappeared.

After dozen of changes, the final settings I ended up with are:

config.action_mailer.delivery_method = :smtp
config.action_mailer.default_url_options = { :host => "my.ip.addr.here" }
config.action_mailer.smtp_settings = {
:address => "smtp.gmail.com",
:port => 587,
:domain => 'my.ip.addr.here:80',
:user_name => "my_email_name@gmail.com",
:password => "my_email_password",
:authentication => :plain,
:enable_starttls_auto => true
}

The above solution provided the correct settings (which I already had) but did not solve the issue. After continued attempts, I kept getting the same error. Turns out, I had to "clear the CAPTCHA" from the web. See the gmail documentation for details.

You can also jump right to the "clear the CAPTCHA" page here.

I had the same problem: emails were sent from development, but not from production (where I was getting Net::SMTPAuthenticationError). This drove me to conclusion that the problem was not with my app's configuration, but with Google.

Reason: Google was blocking access from unknown location (app in production)

Solution: Go to http://www.google.com/accounts/DisplayUnlockCaptcha and click continue (this will grant access for 10 minutes for registering new apps). After this my app in production started sending emails ;)

This solution is working for me:

config.action_mailer.delivery_method = :smtp
config.action_mailer.default_url_options = { host:'localhost', port: '3000' }
config.action_mailer.perform_deliveries = true
config.action_mailer.raise_delivery_errors = true
config.action_mailer.default :charset => "utf-8"
config.action_mailer.smtp_settings = {
:address => "smtp.gmail.com",
:port => 587,
:domain => 'localhost:3000',
:user_name => "xyz@gmail.com",
:password => "password",
:authentication => :plain,
:enable_starttls_auto => true
}

It's true that Google will block your sign-in attempt but You can change your settings at https://www.google.com/settings/security/lesssecureapps so that your account is no longer protected by modern security standards.

go to following link and turn on https://www.google.com/settings/security/lesssecureapps

A lot later but just in case it helps anyone.. Just called Google Apps Help Center and they instructed to change the lesssecureapps setting (as everyone else) but also to change the port to 465.

In my case, that did the trick!

I had the same problem and after some trial and errors, have come to this resolution which is an option to be enabled in google:

Click https://www.google.com/settings/u/0/security/lesssecureapps

Enable 'Access for less secure apps' here by logging in with the email address you have provided in smtp configuration.

Hello this also worked for me and so if someone is still having a problem try this out.

Make sure you have figaro in your gemfile. To save sensitive information such as username and password as environment variables

gem 'figaro'

And in your config/environments/development.rb , paste the codes below using smtp as method delivery

 config.action_mailer.delivery_method = :smtp

SMTP settings for gmail

  config.action_mailer.smtp_settings =
{
:address=> "smtp.gmail.com",
:port => 587,
:user_name => ENV['gmail_username'],
:password=> ENV['gmail_password'],
:authentication=> "plain",
:enable_starttls_auto=>true
}




config.action_mailer.default_url_options = { host: "locahost:3000" }

In your config directory create a file called application.yml and add the codes below.

gmail_username: 'example@gmail.com'
gmail_password: "your_example_email_password_here"

You must use your email and password for authentication in the file.

I also faced the problem, and after some research in Gmail setting, I found the solution:

  1. In gmail, go to settings.

  2. Select "Forwarding and POP/IMAP" tab.

  3. In the IMAP access section, select "Enable IMAP".

The accepted answer seems very old, I don't know if at that time the followin (better) solution was existing:

Now, sending emails works perfectly!

To resolve this issue:

  • If you see: Net::SMTPAuthenticationError (535-5.7.8 Username and Password not accepted.), then you need to allow less secure apps to login your google account. To enable less secure apps login follow: https://myaccount.google.com/lesssecureapps?. But will allow all apps to login. If you want to customize it refer : https://support.google.com/a/answer/6260879?hl=en

  • Then may be possible you will get Net::SMTPAuthenticationError (534-5.7.14), so to resolve this refer: pli=1http://www.google.com/accounts/DisplayUnlockCaptcha. After that click the continue from the page you get redirected. It will verify your Captcha and your app will get verified to use your google account to send emails.

NOTE: Please make sure you'r using correct credentials of your gmail account.

If you'r not willing to allow all the apps please refer: https://support.google.com/a/answer/6260879?hl=en. From the link go to Use alternatives to less secure apps, this will guide you to an alternative way to Allow Less Secure apps access to your google account.
