外贸网站必备：为什么必须安装SMTP插件？2023最全指南
没有SMTP插件，外贸网站将面临邮件收发难题
Without SMTP plugins, foreign trade websites will face email delivery problems
很多外贸新手问我："只要安装好WordPress网站，就能正常收发客户邮件吗？"我的回答总是：请务必安装SMTP插件。
Many beginners in foreign trade ask me: "Can I send and receive customer emails normally just by installing a WordPress website?" My answer is always: You must install an SMTP plugin.
这是因为大多数主机服务商对25端口有严格限制，导致WordPress网站无法直接收发邮件。SMTP插件（Simple Mail Transfer Protocol）就是解决这个问题的关键。
This is because most hosting providers have strict restrictions on port 25, making WordPress websites unable to send and receive emails directly. SMTP plugins (Simple Mail Transfer Protocol) are the key to solving this problem.
