无法使用smtp.gmail.com，vbscript端口587发送邮件

Question

我正在尝试使用vbs脚本发送邮件，但它不起作用。我正在使用服务器smtp.gmail.com和端口587.当我将端口更改为25时，这是有效的。下面是我正在使用的代码：

    SMTPMail "to", "cc", "TEST", "TEST"


Function SMTPMail(ByVal sTo, ByVal sCc, ByVal sSubject, ByVal sBody)


    Const cdoSendUsingPickup = 1 'Send message using the local SMTP service pickup directory. 
    Const cdoSendUsingPort = 2 'Send the message using the network (SMTP over the network).

    Const cdoAnonymous = 0 'Do not authenticate 
    Const cdoBasic = 1 'basic (clear-text) authentication 
    Const cdoNTLM = 2 'NTLM

    Dim objMessage

    set objMessage = CreateObject("CDO.Message")
    objMessage.Subject = sSubject
    objMessage.Sender = "sender"
    objMessage.From = "from"
    objMessage.To = sTo
    objMessage.CC = sCc
    objMessage.TextBody = sBody


    '==This section provides the configuration information for the remote SMTP server.

    objMessage.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2

    'Name or IP of Remote SMTP Server 
    objMessage.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "smtp.gmail.com"    

    'Server port (typically 25) 
    objMessage.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpserverport") = 587 

    'Type of authentication, NONE, Basic (Base64 encoded), NTLM 
    objMessage.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate") = 1

    'Your UserID on the SMTP server 
    objMessage.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/sendusername") = "username"    

    'Your password on the SMTP server 
    objMessage.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/sendpassword") = "password"    

    'Use SSL for the connection (False or True) 
    objMessage.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpusessl") = True

    'Connection Timeout in seconds (the maximum time CDO will try to establish a connection to the SMTP server) 
    objMessage.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpconnectiontimeout") = 60

    objMessage.Configuration.Fields.Update()
    objMessage.Send()

End Function

提前谢谢。

Gmail用户可以在官方网站上访问其帐户，也可以使用第一方或第三方应用和服务。第一方应用程序是Google的Android官方Gmail应用程序，而Thunderbird和Windows 8的邮件客户端应用程序是第三方应用程序。

Google announced早在2014年4月，它将改善其服务的登录安全性，并影响向公司发送用户名和密码的任何应用程序。

该公司建议当时切换到OAuth 2.0，但直到现在才强制执行。

如果您在Google上的安全设置下打开新的less secure应用页面，您会发现Google默认禁用了访问权限。

注意：只有在您未使用Google Apps或已为该帐户启用双因素身份验证时才能看到该页面。

您可以在此处翻转开关以再次启用安全性较低的应用程序，以便重新获得访问权限。

端口使用的另一件事是 465 而不是 587 所以你可以尝试使用端口 465

为我工作的vbscript

EmailSubject = "Sending Email by CDO"
EmailBody = "This is the body of a message sent via" & vbCRLF & _
        "a CDO.Message object using SMTP authentication ,with port 465."

Const EmailFrom = "self@gmail.com"
Const EmailFromName = "My Very Own Name"
Const EmailTo = "someone@destination.com"
Const SMTPServer = "smtp.gmail.com"
Const SMTPLogon = "self@gmail.com"
Const SMTPPassword = "gMaIlPaSsWoRd"
Const SMTPSSL = True
Const SMTPPort = 465

Const cdoSendUsingPickup = 1    'Send message using local SMTP service pickup directory.
Const cdoSendUsingPort = 2  'Send the message using SMTP over TCP/IP networking.

Const cdoAnonymous = 0  ' No authentication
Const cdoBasic = 1  ' BASIC clear text authentication
Const cdoNTLM = 2   ' NTLM, Microsoft proprietary authentication

' First, create the message

Set objMessage = CreateObject("CDO.Message")
objMessage.Subject = EmailSubject
objMessage.From = """" & EmailFromName & """ <" & EmailFrom & ">"
objMessage.To = EmailTo
objMessage.TextBody = EmailBody

' Second, configure the server

objMessage.Configuration.Fields.Item _
("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2

objMessage.Configuration.Fields.Item _
("http://schemas.microsoft.com/cdo/configuration/smtpserver") = SMTPServer

objMessage.Configuration.Fields.Item _
("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate") = cdoBasic

objMessage.Configuration.Fields.Item _
("http://schemas.microsoft.com/cdo/configuration/sendusername") = SMTPLogon

objMessage.Configuration.Fields.Item _
("http://schemas.microsoft.com/cdo/configuration/sendpassword") = SMTPPassword

objMessage.Configuration.Fields.Item _
("http://schemas.microsoft.com/cdo/configuration/smtpserverport") = SMTPPort

objMessage.Configuration.Fields.Item _
("http://schemas.microsoft.com/cdo/configuration/smtpusessl") = SMTPSSL

objMessage.Configuration.Fields.Item _
("http://schemas.microsoft.com/cdo/configuration/smtpconnectiontimeout") = 60

objMessage.Configuration.Fields.Update
'Now send the message!
On Error Resume Next
objMessage.Send

If Err.Number <> 0 Then
    MsgBox Err.Description,16,"Error Sending Mail"
Else 
    MsgBox "Mail was successfully sent !",64,"Information"
End If
