Question

过去，我通过电子邮件“9990001111@messaging.sprintpcs.com”向我的Sprint电话发送了一条短信，并且它运行良好。现在我认为IT部门已经改变了一些东西，因为它不会经历。我这样说是因为在.NET中没有问题：

    Dim mailClient As New SmtpClient("mail.mycompany.com")

    Dim fromAddress As String = "Me.Developer@mycompany.com"
    Dim toAdddress As String = "9990001111@messaging.sprintpcs.com"

    'subject and body text depend on text message type
    Dim subj As String = "", body As String = ""
    subj = "Warning: Low trip count on 2014-02-06"
    body = "Trip count <= 200. Please review log file."

    With mailClient
        Debug.Print("Host=" & .Host)
        Debug.Print("Port=" & .Port)
        Debug.Print("DeliveryMethod=" & .DeliveryMethod.ToString)
        Debug.Print("EnableSsl=" & .EnableSsl.ToString)
        Debug.Print("UseDefaultCredentials=" & .UseDefaultCredentials)
    End With

    'send the email
    mailClient.Send(fromAddress, toAdddress, subj, body)

在我的公司Outlook客户端中，我可以手动创建电子邮件并将其发送到同一个电子邮件地址，这样就不会有任何问题。

现在在VB6中使用CDO我尝试使用所有相同的属性，但它没有到达。我甚至在一个gmail地址添加了一个CC，它到达那里但不到手机。这是VB6 / CDO代码的样子：

'use CDO to setup an email object
Dim cdoConfig As CDO.Configuration
Dim cdoMessage As CDO.Message
Dim cdofields As Object

'Create new configuration object
Set cdoConfig = New CDO.Configuration
Set cdofields = cdoConfig.Fields
Set cdoMessage = New CDO.Message

With cdofields
    .Item(cdoSMTPServer) = "mail.mycompany.com"
    .Item(cdoSMTPServerPort) = 25
    .Item(cdoSendUsingMethod) = cdoSendUsingPort 'Send the message using the network (SMTP over the network).

    .Item(cdoSMTPAuthenticate) = cdoAnonymous
    .Item(cdoSMTPUseSSL) = False                 'Use SSL for the connection (True or False)
    .Item(cdoSMTPConnectionTimeout) = 60

    'if mail server requires outgoing authentication uncomment the lines below and use a valid email address and password.
    '.Item(cdoSMTPAuthenticate) = cdoBasic 'basic (clear-text) authentication
    '.Item(cdoSMTPAuthenticate) = cdoNTLM
    '.Item(cdoSMTPUseSSL) = True
    '.Item(cdoSendUserName) = "Joe Dirt"
    '.Item(cdoSendPassword) = "doughnuts"

    .Update
End With
DoEvents

'set message configuration
Set cdoMessage.Configuration = cdoConfig

'set message contents
With cdoMessage
    .Sender = "Me.Developer@mycompany.com"
    .From = "Me Developer"
    .Subject = "Warning: Low trip count on 2014-02-06"
    .TextBody = "Trip count <= 200. Please review log file."
    .To = "9990001111@messaging.sprintpcs.com"
    .CC = "me.developer@gmail.com"
End With

'send message
cdoMessage.Send

无法弄清楚为什么它适用于.NET和本机Outlook，而不适用于VB6 / CDO。

Answer 1

看起来您正在使用CDO通过mail.mycompany.com中继邮件。 mail.mycompany.com的邮件服务器日志应显示a）mail.mycompany.com是否收到了来自您的应用程序的消息，如果是，b）是否成功发送到9990001111@messaging.sprintpcs.com。如果，日志不应显示失败的原因。从邮件服务器日志中，您应该能够找出问题。

SMS电子邮件不适用于VB6 / CDO
