Lumen 5.5 Mailer

Lumen 沒有內建 Mailer 的功能

Note: By default, the illuminate/mail package is not included with Lumen, so you will need to add the illuminate/mail dependency in your composer.json file.

似乎沒什麼選擇
只有從 Laravel 移植過來的 illuminate/mail

如果直接使用 composer require illuminate/mail 會出錯
因為有太多版本了
建議還是從 composer.json 下手
將 "illuminate/mail": "^5.5" 加入

不過這時候執行 composer update 還是會出錯

egulias/email-validator suggests installing ext-intl (PHP Internationalization Libraries are required to use the SpoofChecking validation)
illuminate/mail suggests installing aws/aws-sdk-php (Required to use the SES mail driver (~3.0).)
illuminate/mail suggests installing guzzlehttp/guzzle (Required to use the Mailgun and Mandrill mail drivers (~6.0).)
Writing lock file
Generating autoload files

還需要把 aws & guzzlehttp 的套件加入

"aws/aws-sdk-php": "~3.0",
"guzzlehttp/guzzle": "~6.0"

這時候執行 composer update 就沒問題了
