PHPMailer无法验证邮件服务器通过
公司换了邮件服务器，本来是用U-MAIL的。现在换用微软的那个exchange。

结果原来的php脚本连接新的邮件服务器失败，提示是：Could not authenticate。

大家帮忙诊断下可能是哪里有问题？

注：脚本只修改了连接的$mail->Host。别的用户名和密码都没变。而且用outlook连接验证，新邮箱的IP，用户名，密码都是可以用的。

------解决方案--------------------
是否要求SSL?

对比对比, 自己的php是否安装了openssl，账号密码，smtp服务器这个ip+port是否ssl。

PHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

PHP Performance: Identifying and Fixing BottlenecksMay 11, 2025 am 12:13 AM

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.
