When making a notification system, According to business needs, use different accounts to send emails according to different scenarios.

##The method is as follows: Create email account configuration file/config/my_emails.php

<?php
return [
 &#39;emails&#39; => [
  &#39;a&#39; => [
   &#39;email&#39; => &#39;a@188.com&#39;,
   &#39;password&#39; => &#39;专属客户端密码&#39;,
   &#39;smtp&#39; => &#39;smtp.188.com&#39;,
   &#39;port&#39; => &#39;465&#39;,
   &#39;encryption&#39; => &#39;ssl&#39;,
   &#39;name&#39; => &#39;靓仔A&#39;,
  ],
  &#39;b&#39; => [
   &#39;email&#39; => &#39;b@188.com&#39;,
   &#39;password&#39; => &#39;专属客户端密码&#39;,
   &#39;smtp&#39; => &#39;smtp.188.com&#39;,
   &#39;port&#39; => &#39;994&#39;,
   &#39;encryption&#39; => &#39;ssl&#39;,
   &#39;name&#39; => &#39;靓女b&#39;,
  ],
 ],
];

Next create the switching assistant class

<?php
namespace App\Mail;
use Illuminate\Support\Facades\Mail;
 
class MailHelper
{
 public static function setAccount($accountName)
 {
  $transport = new \Swift_SmtpTransport(
   config("my_emails.emails.{$accountName}.smtp"),
   config("my_emails.emails.{$accountName}.port"),
   config("my_emails.emails.{$accountName}.encryption")
  );
  $transport->setUsername(config("my_emails.emails.{$accountName}.email"));
  $transport->setPassword(config("my_emails.emails.{$accountName}.password"));
  $mailer = new \Swift_Mailer($transport);
  Mail::setSwiftMailer($mailer);
  Mail::alwaysFrom(config("my_emails.emails.{$accountName}.email"), config("my_emails.emails.{$accountName}.name"));
 }
}

The actual usage is as follows:

<?php
MailHelper::setAccount(&#39;a&#39;);
Mail::to(&#39;boy@163.com&#39;)->send(new TestMail());
MailHelper::setAccount(&#39;b&#39;);
Mail::to(&#39;girl@163.com&#39;)->send(new TestMail());
