Android Question Error 503 Bad sequence of commands in smtp send email

[joaquinortiz]

I have the following code and when I send an e-mail attaching a file, it shows me this message.

            '///////////////////////////////////////////////////
            myEmail.gEmailTO = txtEmailTo.Text
            '///////////////////////////////////////////////////
            'Asigna el nombre del archivo
            lExcelFileName = myGlobalVariables.gExcelQuickSCAN & "_" & fechahoy & TimeHoy & ".xls"
'            fcnExportaEntradas(lExcelFileName)
            myAccess.ExportaReciboCiegoEXCEL(lQuery,lExcelFileName)
            ''''''''''''''''''///////////////////////////
            Dim mail As SMTP
            mail.Initialize(myEmail.gServerOUT,myEmail.gPortOUT,myEmail.gEmailFROM,myEmail.gEmailPassword,"mail")
            mail.AddAttachment(myGlobalVariables.gSQLDataBasePath,lExcelFileName)
            mail.UseSSL = True
            mail.To.Add(myEmail.gEmailTO)
            mail.HtmlBody = True
            mail.Body = myEmail.gEmailBODY 'html.ToString
            myEmail.gEmailSubject = myGlobalVariables.gSistema & " - Archivo adjunto " & lExcelFileName
            mail.Subject = myEmail.gEmailSubject 'title
            Dim obj As Object = mail.Send
            wait for (obj) mail_MessageSent(Success As Boolean)
            If Success Then
'                blnSendFile = True
'                'ToastMessageShow("Enviado correctamente",False)
                Msgbox2Async("Se envió el archivo excel " & lExcelFileName & " al correo: " & txtEmailTo.Text.Trim, myGlobalVariables.gSistema, "Si", "", "No", Null, False)
                Wait For Msgbox_Result (Result As Int)
                If Result = DialogResponse.POSITIVE Then
                    SalirFormulario

            Else
                Msgbox2Async("No se pudo enviar el archivo excel: " & CRLF & LastException.Message, myGlobalVariables.gSistema, "Si", "", "No", Null, False)

I'll already check it....let me check it again.

But, there is something that i'm confused.

For example.
IF my sender e-mail is: myemail@basicwms.com
And my to e-mail is: myemail@gmail.com or myemail@id-consultores.com

It shows me this error.

But if I change my e-mailTo to myemail2@basicwms.com <-- It's works and I recieve the e-mail.

What could be the problem?

 

[JohnC]

Try adding this line:

mail.MailFrom = "myemail@basicwms.com"

 

[joaquinortiz]

Try adding this line:

mail.MailFrom = "myemail@basicwms.com"

It doesn't work.

 

[joaquinortiz]

Now, I'm recieveing the following error.

org.apache.commons.net.smtp.SMTPConnectionClosedException: Connection closed without indication

 

[ilan]

But if I change my e-mailTo to myemail2@basicwms.com <-- It's works and I recieve the e-mail.

are you sure that the settings are correct for gmail?

 

[joaquinortiz]

are you sure that the settings are correct for gmail?

Yes, it's correcto.

The receiver can be: joaquinortiz29@gmail.com or jortiz@id-consultores.com

The sender that I'm using is 'no-reply@basicwms.com'

mail.Initialize("basicwms.com",465,"no-reply@basicwms.com","mypassword","mail")
mail. UseSSL = True

With this, the error still Error 503 Bad sequence...etc, etc.
I recently talked to my emails provider, and he told me the following.

If the e-mail is not authenticated with the basicwms mail user and mail password then it can only send to the same domain and not outside, but apparently, you are sending it authenticated, check it well and google what may be happening.

Also I tried the following:
mail.Initialize("basicwms.com",587,"no-reply@basicwms.com","mypassword","mail")
mail.StartTLSMode = True

And it throws me the following error:
java.net.ConnectException: Connection Timed out.

 

[JohnC]

Try commenting out the mail.StartTLSMode = True line, and add this line:

Mail.AuthMethod = mail.AUTH_LOGIN

Did you fix the issue?
