解释：
第一个参数为邮箱路径名(暂时没弄明白)  第二个参数为邮箱名
"*": 列出有层级关系的(包含子邮箱的)  "%": 只列出本级邮箱名(不包含旗下的子邮箱)
LIST “” “rubbishs” 列出垃圾箱
这个命令式迅速返回的,没有任何延时或者其他标签性处理。

//同上

* LSUB () "/" "trash"
* LSUB () "/" "&XfJT0ZABkK5O9g-"
* LSUB () "/" "&g0l6Pw-"

解释：
只显示SUBSCRIBE命令设置的邮箱(文件subscriptions中提到的邮箱名)

//给指定邮件添加标记

* 1 FETCH (FLAGS (\Deleted \Seen))
Q6 OK Store completed.

Q7 STORE 1 +FLAGS (\Flagged)

Q7 OK Store completed.
解释：mail-id:1是邮件编号并不是邮件的uid 这个一定要清楚，如果邮箱中有3封邮件，邮件编号就是1、2、3

//取邮件 
Q8 FETCH 1 flags
* 1 FETCH (FLAGS (\Deleted \Seen))

Q9 FETCH 1 full

解释：FETCH的应用很复杂，用到那个说那个

//拷贝
Q12 UID COPY 95 INBOX
Q12 UID COPY 95 INBOX
* 6 EXISTS
* 3 RECENT

解释：imap协议中没有move和delete命令，是通过命令组合实现的功能：
move: 1：copy到目的邮件夹
           2：store id +flags (\Deleted)
           3：expunge
彻底删除delete:
            1:store id +flags (\Deleted)
            2: expunge
删除到垃圾箱delete:
             实际上是做move 如上的操作copy->trush



//上传邮件到邮箱
