MessageId & EmailId

messageId 是提交一次 SMTP 請求，返回的消息編號。

emailId 是 EngageLab 投遞一封郵件，返回的郵件編號，可以對應到某一次請求的某一個收件人。

兩者的計算關係如下：

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 不做位數補齊 * 無論 to 中是否含有重複的值，返回的 emailId list 跟發送清單的順序都是相同的。

          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 不做位數補齊
* 無論 to 中是否含有重複的值，返回的 emailId list 跟發送清單的順序都是相同的。
