<div>我使用io::socket，实现了server和client之间的通信</div>
<div>目前碰的一个问题，从client这段发送命令到server这边，当同时又2个client发送指令到server上去的话，将会按照指令发送的先后依次执行，我希望做到，当正在执行时，又有指令发送到server上，同时也开始执行相应操作，而不是等前一个指令的操作全部完成后，才开始</div>
<div>简单的说，也就是希望可以同时收到不同client上传来的指令，server上同时执行这些指令操作<br><br> </div>

<p><span>首先需要指出的是</span><span lang="EN-US">:gmail </span><span>所使用的端口不是默认的</span><span lang="EN-US"> SMTP </span><span>端口</span><span lang="EN-US">25, </span><span>而是端口</span><span lang="EN-US">465,</span><span>而且也不是普通的</span><span lang="EN-US">smtp</span><span>连接，而是带</span><span lang="EN-US">ssl</span><span>的</span><span lang="EN-US">smtp</span><span>（有关信信息在</span><span lang="EN-US">gmail</span><span>的帮助中的邮件客户端设置可以看到）。</span><span lang="EN-US"><br>

</span><span>另外一个问题是</span><span lang="EN-US">:</span><span>在认证之前你应该给</span><span lang="EN-US">smtp</span><span>服务器发送一个</span><span lang="EN-US">ELHO</span><span>命令，即先</span><span lang="EN-US">$smtp->hello(),</span><span>然后才是</span><span lang="EN-US">$smtp-> auth();</span><span>关于</span><span lang="EN-US">smtp</span><span>协议的细节</span><span lang="EN-US"><br>
</span><span>你有时间的话可以看一下相关的</span><span lang="EN-US">rfc</span><span>文档，可以在</span><span lang="EN-US">google</span><span>搜索</span><span lang="EN-US">" smtp rfc "</span><span>，这样你会对邮件发送的细节有个清楚的认识。</span><span lang="EN-US"><br>
