有时在本地主机的gmail端口465或587上，PHPMailer无法正常工作 [英] PHPMailer do not work properly sometimes on gmail port 465 or 587 on localhost
问题描述
我正在使用 LOCALHOST 上的最新版本的 PHPMailer 6.0.2 和Gmail SMTP端口[465上的 SSL 和 TLS 587 ].它运作良好，但不稳定或无法正常运行，这很奇怪，而OpenConfig扩展在PHP Config/PHP.ini文件中也处于活动状态.
I am using the latest version of PHPMailer 6.0.2 on LOCALHOST with Gmail SMTP Ports [ SSL on 465 and TLS 587 ]. It works well but not stable or works properly, very strange while OpenSSL Extension is also active in PHP Config /PHP.ini file.
有时会在465或587端口上返回错误" SMTP错误:无法连接到SMTP主机".
It returns the error " SMTP Error: Could not connect to SMTP host ", sometimes on 465 or 587 port.
现在是587.
这是端口587上的确切错误；
