无法使用 codeigniter 使用 mailgun smtp 发送邮件

Question

我正在尝试使用 codeigniter 电子邮件库和 mailgun smtp 发送电子邮件。 smtp 设置是正确配置的，我不知道可能是什么问题....

这里是php代码：

$config['mailtype'] = 'html';
$config['charset'] = 'utf-8';

$config['protocol'] = 'smtp';
$config['smtp_host'] = 'smtp.mailgun.org';
$config['smtp_port'] = 25;
$config['smtp_user'] = 'user@user.com';
$config['smtp_pass'] = 'thepasswordconfiguredinmailgun';
$config['smtp_timeout'] = '4';
$config['crlf'] = '\n';
$config['newline'] = '\r\n';

$this->email->initialize($config);
$this->email->clear(TRUE);
$this->email->from('office@test.com', 'FromName');
$this->email->to('myemail@yahoo.com');

$this->email->subject('Subiect de test');
$this->email->message('Testez sa vad daca merge si daca pot sa trimit. Daca nu pot de ce nu pot ?');

$this->email->send();
echo $this->email->print_debugger();

我遇到以下错误：

Answer 1

通过检查Mailgun's documentation:

这通常是由互联网服务提供商 (“ISP”) 阻止端口 #25 引起的。如果您使用的是住宅 ISP，这往往会发生。

要检查这一点，请尝试在命令行中运行 telnet：

telnet smtp.mailgun.org 25

如果端口 25 未被阻塞，您应该会看到如下内容：

Trying 174.37.214.195...
Connected to mxa.mailgun.org.
Escape character is '^]'.
220 mxa.mailgun.org (Mailgun)

如果你没有看到这个，那么你就被屏蔽了。有几种解决方法：

1. 使用 HTTP API 发送
2. 尝试使用端口#587 或#2525

Answer 2

问题出在我的共享主机提供商上。他们不接受与外部 smtp 邮件提供商的连接的接缝。但是我会接受 sotoz 的回答，因为我会使用 http api 发送它们！
