------ Solution --------------------
The main problem is to understand the features supported by each mail system, such as whether pop is supported and whether ssl/tls is supported, which can be handled separately based on the actual situation. Phpmailer is recommended for good encapsulation.
------ Solution --------------------
It is estimated that it is a problem with people's mail servers. I don't want you to do this.
