使用 cdo.message 发送电子邮件时指定我自己的 message-id header

Specify my own message-id header when sending email with cdo.message

有没有办法用 CDO 指定我自己的 message-id?

使用下面的配置,message-id仍然是cdo组件生成的,忽略我指定的

<%
Const cdoSendUsingPort = 2

Dim iMsg, iConf, Flds
Set iMsg = CreateObject("CDO.Message")
Set iConf = CreateObject("CDO.Configuration")
Set Flds = iConf.Fields

' set the CDOSYS configuration fields to use port 25 on the SMTP server
With Flds
    .Item("http://schemas.microsoft.com/cdo/configuration/sendusing") = cdoSendUsingPort
    .Item("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "smtp@example.com"

    .Item("urn:schemas:mailheader:message-id") = "0123456789.0123456789@example.com"
.Update
End With

With iMsg
    Set .Configuration = iConf

    .From = "from@example.com"
    .Subject = "test"
    .To = "to@example.com"
    .HTMLBody = "test"
    .Send
End With
Set iMsg = Nothing
Set iConf = Nothing
Set Flds = Nothing
%>

配置objectiConf与消息无关objectiMsg, 你不需要创建它。

因此,删除 Set iConf = CreateObject("CDO.Configuration") 并将 Set Flds = iConf.Fields 替换为 Set Flds = iMsg.Fields

您需要使用iMsg.Fields为消息设置headers。

Setting Message Header Fields

Dim iMsg, iConf, Flds
Set iMsg = CreateObject("CDO.Message")
Set Flds = iMsg.Fields
Set iConf = CreateObject("CDO.Configuration")
Set Flds = iConf.Fields

' set the CDOSYS configuration fields to use port 25 on the SMTP server
With Flds
    .Item("http://schemas.microsoft.com/cdo/configuration/sendusing") = cdoSendUsingPort
    .Item("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "smtp.example.com"
    .Update
End With

With iMsg.Fields
    .Item("urn:schemas:mailheader:message-id") = "0123456789.0123456789@example.com"
    .Update
End With

With iMsg
    Set .Configuration = iConf

    .From = "from@example.com"
    .Subject = "test"
    .To = "to@example.com"
    .HTMLBody = "test"
    .Send
End With
