MessageId & EmailId

messageId 是提交一次 SMTP 请求，返回的消息编号。

emailId 是 EngageLab 投递一封邮件，返回的邮件编号，可以对应到某一次请求的某一个收件人。

两者的计算关系如下：

to = [A, B, C] emailId_A = messageId + to.index(A) + '$' + A emailId_B = messageId + to.index(B) + '$' + B emailId_C = messageId + to.index(C) + '$' + C # 注意： * position 不做位数补齐 * 无论 to 中是否含有重复的值，返回的 emailId list 跟发送列表的顺序都是相同的。

          to = [A, B, C]
emailId_A = messageId + to.index(A) + '$' + A
emailId_B = messageId + to.index(B) + '$' + B
emailId_C = messageId + to.index(C) + '$' + C

# 注意：
* position 不做位数补齐
* 无论 to 中是否含有重复的值，返回的 emailId list 跟发送列表的顺序都是相同的。
