Hermes Emailing [v1.0.0]

Highly configurable multi-process emailing solution (console command) for yii2.0.

Installation

1. Downloading

The preferred way to install this extension is through composer.

Either run

php composer.phar require --prefer-dist thinker-g/yii2-hermes-mailing:dev-master

or add

"thinker-g/yii2-hermes-mailing": "dev-master"

to the require section of your composer.json file.

You could also download a copy directly from the GitHub project page. If you do in this way, you'll be needing to setup the directory of alias @thinker_g/HermesMailing. Here's an example.

In config/main.php, assume that you put yii2-hermes-mailing folder in extensions/ of your project:

return [
    'id' => 'app-console',
    ...
    'aliases' => [
        '@thinker_g/HermesMailing' => '@app/extensions/yii2-hermes-mailing',
        ...
    ],
    ...
];

In the example @app is the app's root alias, which will be replaced by its real path. It could be '@common', '@frontend', '@backend' in an advanced template.

2. Installing

a) Configuring

Edit the configuration file of your console appliction ( console/config/main.php / config/console.php by default) to mount the console command controller.

return [
    'id' => 'app-console',
    ...
    'controllerMap' => [
        'email' => [
            'class' => 'thinker_g\HermesMailing\console\DefaultController',
            'modelClass' => 'common\models\HermesMail',
            'installerMode' => true,
            'testMode' => true
        ],
        ...
    ],
    ...
];

Please be noticed that modelClass will be used by the command later to generate the AR model, its default value is app\\models\\HermesMail. If you are using a basic yii2.0 template or just want to keep the model in model directory of the console application, you don't need to specify the modelClass. Here we assume that we are using the default advanced yii2.0 template. And of course, you can specify any model name as you want.

Set installerMode to true will enable some helper actions that will only be used during installation. And it should be set to false (or be removed as false is default) when the command is ready for real usage.

testMode is a helper option for testing performace and adjusting parameters. When it's enabled, the real "send" operation will randomly return true or false. Except this, all other operations will be performed normally.

b) Initializing (creating database table and generating AR model)

Be sure that your 'db' application component is functioning, then we can issue the command below to initialize the command. The default initialization will create a table named hermes_mail and its corresponding AR model with the name you specifed above.

user@localhost:~/ws/advanced$ ./yii email/install

You should be seeing this if the command is installed successfully and ready for using.

user@localhost:~/ws/advanced$ ./yii email/install
Create table hermes_mail? (yes|no) [no]:y
Migrating database...
    > create table hermes_mail ... done (time: 0.065s)
Running 'Model Generator'...

The following files will be generated:
        [new] /home/admin/ws/advanced/common/models/HermesMail.php

Ready to generate the selected files? (yes|no) [yes]:y

Files were generated successfully!

model/default"...

done!

Install complete!
user@localhost:~/ws/advanced$

c) Fill up some test data

Up to now your program is ready. You could use the generated AR model anywhere in your code, to insert emails to the queue. To facilitate testing, you could use email/fill4test command to prepare(insert) 1000 emails for test.

user@localhost:~/ws/advanced$ ./yii help email/fill4test

DESCRIPTION

Run to insert a certain number of test email entries.


USAGE

yii email/fill4test [insertCount] [from] [to] [...options...]

- insertCount: int (defaults to 1000)
  Number of emails to insert.

- from: string (defaults to 'from_{seq}@example.com')
  From address where the token "{seq}" will be replaced by the sequence number.

- to: string (defaults to 'to_{seq}@example.com')
  To address where the token "{seq}" will be replaced by the sequence number.

Let's say we want 500 emails to give a try:

user@localhost:~/ws/advanced$ ./yii email/fill4test 500
An example email has been appended to the email queue. ID: 1.
An example email has been appended to the email queue. ID: 2.
...
An example email has been appended to the email queue. ID: 500.
===================================================================== 100%
500 mails inserted.

Now let's move on to run something real.

Usage

Check before taking off:

*** ATTENTION! Please check following items before you run the test. This will ensure your emails inserted above won't be sent out. ***

• InstallerMode is off. (installerMode => false)
• Test mode is on. (testMode => true)
• Your "mailer" application component is functioning.

Once the extension is installed, simply use it in your code by :

user@localhost:~/ws/advanced$ ./yii email/send-queue

If you are seeing some output like this, your command is working. And you can deploy it by configuring your crontab.

CRONTAB

Please do not forget to disable testMode before you setup crontab for real emailing. Here's an example of crontab seeting for webmaster user.

 ================== hermes mailing ==================
 * * * * * sleep  0;/home/webmaster/yii2Adv/yii email/send-queue >> /home/webmaster/yii2adv/console/logs/send-queue-0

 ================== hermes mailing ==================

This setting will start a new emailing process every 10 seconds, every process will work parallely till all mails are sent in the queue.

Advanced Configuration

Under development, coming soon!

This part will cover a batch of interesting features:

• Sending control (Indirect control of memory consumption and execution time.)
• Distributed deployment
• Using dedicated email database service
• Complying spamming rules
• Customization (replacing mailer, AR, etc.)
• Handling events

Please, temporarily, read the property comments in the code for usage of them.
