Unix上的PHP邮件队列异常 - 专家意见

Question

I am using Mail Queue to send emails in my application (https://pear.php.net/package/Mail_Queue/)

The same code works fine on windows (php version: 5.5.28) and it gives the below mentioned exception on unix (php version 5.6)

PHP User Notice 'yii\base\ErrorException' with message 'Error in sending mail: authentication failure [SMTP: STARTTLS failed (code: 220, response: Begin TLS negotiation now)]'

The mail server credentials are fine. They are same on linux as well as on windows. Code 220 means the server is ready (via http://www.serversmtp.com/en/smtp-error)

I read somewhere it is due to php5.6 and it will work fine on 5.5 but I don't think so that would be a valid answer/solution to the problem.

Answer 1

I guess this is because PHP 5.6 does SSL peer verification by default and PHP 5.5 doesn't. I guess if you fix a valid SSL certificate it should work, or disable ssl verify-peer in your code.

Without knowledge of Mail_Queue I don't know how to fix it without any example code.
