PHP Zend - 连接到 SMTP 超时

Question

祝大家美好的一天。

我有以下问题：

我有一个 cron 向使用 zend mailer 发送一些邮件的脚本发送请求。

在测试机上运行没有任何问题。问题是在生产机器上我收到以下错误：

xception 'Zend_Mail_Protocol_Exception' with message 'Connection timed out' in /var/www/html/site/include/Zend/Mail/Protocol/Abstract.php:254
Stack trace:
#0 /var/www/html/bca/include/Zend/Mail/Protocol/Smtp.php(167): Zend_Mail_Protocol_Abstract->_connect('tcp://182.19.13...')

#9 /var/www/html/bca/public_html/index.php(660): Zend_Controller_Front->dispatch()

我运行的 cron 是：

wget -O - -t 1 https://www.site.ro/newsletter/process --no-check-certificate

或类似的

wget -O - -t 1 http://www.site.ro/newsletter/process

当我第一次收到问题时，我告诉他们检查 SMTP 配置，但是 ppl。配置坚持认为配置没问题。所以...我不知道。似乎缺乏连接，但他们仍然坚持认为没问题。有什么帮助吗？

嗯...我不知道他们做了什么...但现在他们得到了这个：

exception 'Zend_Mail_Protocol_Exception' with message '5.3.3 AUTH mechanism LOGIN not     available ' in /var/www/html/bca/include/Zend/Mail/Protocol/Abstract.php:408 Stack     trace:

#10 /var/www/html/bca/public_html/index.php(660): Zend_Controller_Front->dispatch() 
#11 {main}

我建议检查用户/通行证...第七次...他们仍然说可以。

Answer 1

我将通过在服务器上的命令提示符下运行以下命令来验证是否可以从生产服务器联系 SMTP：

$ telnet 1.2.3.4 25

其中 1.2.3.4 是您尝试连接的 SMTP 服务器的 IP 地址或主机名。从异常来看，这个地址开始 182.19.13...

当您运行命令时，您应该看到类似的内容：

Connected to foo.
Escape character is '^]'.
220 foo ESMTP Postfix (Ubuntu)

如果您没有看到类似的内容，请发布输出/错误
