I want to use Mailgun in my Rails application.
When I include through Heroku addon it display error to add credit card number though I wanted the free version.
I looked up and found this code from Mailgun. Could someone tell me how to use it?
require 'mail'
Mail.defaults do
delivery_method :smtp, {
:port => 587,
:address => "smtp.mailgun.org",
:user_name => "",
:password => "",
}
end
mail = Mail.deliver do
to 'bar#example.com'
from 'foo#YOUR_DOMAIN_NAME'
subject 'Hello'
text_part do
body 'Testing some Mailgun awesomness'
end
end
I tried using this but it displays an error - mailgun SSL_read: sslv3 alert bad record mac
You need to sign up with Mailgun and get your SMTP username and password which you would use in the mail configuration.

Summary:
I tried to obtain AWS Cognito User name (OAuth2 from Google) with Perl module Paws::CognitoIdp::GetUser but I failed the code:
my $GetUserResponse = $cognito_idp->GetUser(
AccessToken => 'MyTokenModelType',
);
with the error Invalid Access Token.
Environment
I am developing Web service with following environment:
AWS + EC2 + Ubuntu 20.04 + nginx 1.20.1 + Perl 5.30.0
Using Cognito with Google OAuth2.0
What I can do now
When you access my Web service, Sign In with Google button will appear. If you click it, you can run my Perl CGI script.
What I cannot do now
I want to obtain your Google user name and mail address, but I cannot.
What I did
I wrote the following code:
my $cognito_idp = Paws->service('CognitoIdp',
region => "ap-northeast-1",
max_attempts => 3,
);
my $GetUserResponse = $cognito_idp->GetUser(
AccessToken => 'MyTokenModelType',
);
my $uname = $GetUserResponse->Username;
Then...
When I access my Web service, it failed with the Software error:
Software error:

For help, please send mail to this site's webmaster, giving this error message and the time and date of the error.
Maybe...
I referred following to the documentation
Maybe 'MyTokenModelType' is just the placeholder and I should specify the correct code.
But I don't know how I can make it.
In addition, I want to know how can I obtain not only user name but also user email address.
(Additional Info 2021-11-12)
Thanks to the comment, I read the article:
How to generate access token for an AWS Cognito user?
and I hacked AWS CLI command but I have not got the answer yet.
I think I got to do $ aws connito-idp initiate-auth but I cannot find what arguments I should pass.
In the AWS => Cognito => Users and groups menu, I see the entry of a user of my Web app.
Username: google_??????????
Enabled: Enabled
Account status: EXTERNAL_PROVIDER
Email: (users_email)
I changed my code like this for the experiment to find what information my Web app has.
use Data::Dumper;
my $cognito_idp = Paws->service('CognitoIdp',
region => "ap-northeast-1",
max_attempts => 3,
);
# my $GetUserResponse = $cognito_idp->GetUser(
# AccessToken => 'MyTokenModelType',
# );
# my $uname = $GetUserResponse->Username;
print "Content-type: text/html\n\n\n";
print '<!DOCTYPE html>';
print '<html><pre>';
print Dumper $cognito_idp;
print '</pre></html>';
and I see the contents of $cognito_idp like this:
$VAR1 = bless( {
'_region_for_signature' => 'ap-northeast-1',
...
'credentials' => bless( {
...
'selected_provider' => bless( {
'expiration' => 1636712506,
'actual_creds' => {
'Type' => 'AWS-HMAC',
'SecretAccessKey' => '??????????????',
'Code' => 'Success',
'AccessKeyId' => '???????????????',
'LastUpdated' => '2021-11-12T03:54:16Z',
'Token' => '?????????????????????????????????????',
'Expiration' => '2021-11-12T10:21:46Z'
},
...
I hope I could get the information of the user from the data above.
My question is, how I can specify the MyTokenModelType value of the code:
my $GetUserResponse = $cognito_idp->GetUser(
AccessToken => 'MyTokenModelType',
);
Still I want your info.
Thanks again.
I'm using mailgun with ActionMailer like this:
config.action_mailer.delivery_method = :mailgun
config.action_mailer.mailgun_settings = {
api_key: 'key-b46eXXXXXXXXXXXX91c4',
domain: 'mg.eagle.com'
}
Mails go out like this:
mail(to: #contact, subject: 'Ask a Question', reply_to: #email, from: #email)
How can I add tags to my mails? There is an example in the mailgun documentation (https://documentation.mailgun.com/en/latest/user_manual.html#tagging) but that doesn't use ActionMailer but a POST on the API...
I found the solution to this, it's actually pretty simple:
Put the following line before the mail command:
headers['X-Mailgun-Tag'] = 'contact_us'
However this will only work if the Pull request is merged:
https://github.com/mailgun/mailgun-ruby/pull/133
Until then you can use this in the Gemfile:
gem 'mailgun-ruby', :github => 'mailgun/mailgun-ruby', :branch => 'sjohn/railgun-mailer-headers'
I would like to use the AWS SES mail service using SMTP. I know it works for some versions, but I haven't gotten it to work for my application yet. I get a 530 Authentication error.
My question is in three parts:
1. Does AWS smtp work using Grails 2.3.1 with the Mail 1.0.7 plugin using java 1.7?
If it does work, how does one configure it?
If it does work, how can I get more debug information to figure what is wrong?
I've tried every configuration example variant I've come across for this. My latest is below. (It's clear I don't really understand the Mail plugin and the Java mail class, I'm just trying to suss out a working configuration incantation.)
Here is what I have in my config.groovy file:
grails {
mail {
host = 'email-smtp.us-east-1.amazonaws.com'
port = '587'
username = SMTP AWS username, not IAMS username
password= SMTP AWS password, not IAMS password
props = [ 'mail.debug': true,
'mail.smtp.host' : 'email-smtp.us-east-1.amazonaws.com',
'mail.smtp.auth': 'true',
'mail.smtp.starttls.enable': 'true',
'mail.smtp.port': '587',
'mail.smtp.starttls.required': 'true',
'mail.smtp.user' : smtp username from above,
'mail.smtp.usernme' : smtp username from above,
'mail.smtp.password': smtp password from above,
'mail.smtp.socketFactory.port': '587',
'mail.smtp.socketFactory.class':
'javax.net.ssl.SSLSocketFactory',
'mail.smtp.EnableSSL.enable':'true',
'mail.smtp.socketFactory.fallback': 'false' ]
}
}
I have successfully made direct AWS SES emails using the aws-sdk:1.9.40 plugin, by the way.
I am using the mailService.sendmail code from the Mail plugin. This is unchanged (beyond the hardcoded html text), and works fine when the configuration went to our email server.
def resp = mailService.sendMail {
from replyToEmail
replyTo replyToEmail
to user.email
subject emailSubject
html "This is the mesage text Mar 20"
}
Any help at all would be most appreciated!!
I have followed the instructions of the mailgun, including dots and commas. I installed composer successfully. My domain name is also verified so I wanted to use API for sending emails.
I created a simple application for testing if emails are going or not.
here is the code of sample php application:
<?php
require 'vendor/autoload.php';
use Mailgun\Mailgun;
$mg = new Mailgun("key-********************************");
$domain = "https://api.mailgun.net/v3/mailgun.************.com/messages";
$mg->sendMessage($domain,
array(
'from' => 'noreply#********.com',
'to' => '********#hotmail.com',
'subject' => 'The mailgun is awesome!',
'text' => 'It is so simple to send a message.'));
echo "done";
?>
I get internal server error 500 when I run this file.
When I change the $domain to "mailgun.*****.com" I get emails but in junk folder
I am confused what is happening here.. no apparent fault..
May be some expert will be able to help me out here..
The $domain has to be the same as entered in your settings.
i.e. the domain is mg.domain.com in your mailgun account,
your $domain is domain.com.
Also your from has to be [anything]#domain.com, to be accepted.
I am trying to use the built-in driver for Mailgun to send email. Here's what I have done so far.
Installed Guzzle driver.
Added the following to my config\services.php
'mailgun' => [
'domain' => env('sandbox54d5c9ed96434d689f971fd3.mailgun.org'),
'secret' => env('key-e800aa77cbda23ee8471dd5e'),
],
In my config\mail.php I have added
'driver' => env('MAIL_DRIVER', 'mailgun'),
However, now if I try to do forget password. It says we have sent an email but I don't get anything.
The domain is my sandbox domain name and secret is the API Key.
Am I missing something here or doing something wrong? How can I debug if there are some issues?
Sorry for this late answer, just found your question while googling for something different and hope not too late. If you want to save the credentials in .env, do this in your config\services.php:
'mailgun' => [
'domain' => env('MAILGUN_DOMAIN'),
'secret' => env('MAILGUN_SECRET'),
],
Then in your .env file
MAILGUN_DOMAIN=sandbox54d5c9ed96434d689f971fd3.mailgun.org
MAILGUN_SECRET=key-e800aa77cbda23ee8471dd5e
In the config\services.php you just tell the key on .env file with:
'setting' => env('KEY_IN_ENV')
Laravel will then check if the key found and get the value from .env file:
KEY_IN_ENV = setting_value
Or simply like this in your config\services.php only:
'mailgun' => [
'domain' => 'sandbox54d5c9ed96434d689f971fd3.mailgun.org',
'secret' => 'key-e800aa77cbda23ee8471dd5e',
],
Good for you.
