同安SEO推广专员指南：谷歌竞价广告推广与SMTP插件安装
为什么WordPress网站需要SMTP插件？
Why Does WordPress Need SMTP Plugin?
很多客户询问："安装好WordPress后就能直接收发邮件吗？" 我们的专业建议是：必须安装SMTP插件。
Many clients ask: "Can WordPress send/receive emails directly after installation?" Our professional advice: SMTP plugin is essential.
由于主机服务商对25端口的严格限制，绝大多数WordPress网站无法直接收发邮件。SMTP（简单邮件传输协议）就像邮件中转站：
Due to strict restrictions on port 25 by hosting providers, most WordPress sites cannot send/receive emails directly. SMTP (Simple Mail Transfer Protocol) acts as a mail relay station:
- 客户邮件 → SMTP中转站 → 身份验证 → 您的邮箱
- Client email → SMTP relay → Authentication → Your inbox
这种机制能有效避开垃圾邮件过滤器，送达率提升85%+。
This mechanism effectively bypasses spam filters, increasing delivery rate by 85%+.
