[02/03] Could not access 'CDO.Message' object

[vishalmarya]

i am using the following code to send an email from a asp.net (1.1 ) page

err i am getting is ,

The transport failed to connect to the server.

if i use try catch block then
ex.message returns "Could not access 'CDO.Message' object."

Dim mail As New Mail.MailMessage
        Dim SmtpMail As Mail.SmtpMail
 
        mail.To = "[email protected]"
        mail.From = "[email protected]"
        mail.Subject = "this is a test email."
        mail.Body = "mail body"
        mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", 1) 'basic authentication
        mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername", "sender") 'set your username here
        mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", "mypass") 'set your password here
        mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpserverport", 587)
        mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpusessl", True)
 
        SmtpMail.SmtpServer = "smtp.myserver.com" 
        SmtpMail.Send(mail)

1. the error is generated when i run the aspx page on my dev machine ( win xp pro sp2 iis 5.1)

2. but it works fine if i put the page on my smtp server ( "smtp.myserver.com" )

3. what makes it complicated is , it also works in vs 2005 using net.mail namespace ( on the same machine of case 1 )

somebody got to help me on this.

Thanks.

The "Could not access 'CDO.Message' object." exception is usually a wrapper for a more descriptive exception - have a look at the exceptionInstance.InnerException property, or easier still - Console.WriteLine(exceptionInstance.ToString()), to get the real problem.

that is what i got
----------

System.Web.HttpException: Could not access 'CDO.Message' object. ---> System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Runtime.InteropServices.COMException (0x80040213): The transport failed to connect to the server. --- End of inner exception stack trace --- at System.RuntimeType.Inv...........

i was using the gmail smtp server. so i was supposed to use port 465 or 587.
right ?

after banging my head for so long , just came to my mind to use default port

that is 25 , it worked

but how come , it is working on port 587 in vs 2005 on the same machine
that i cannot understand

Quite possibly may have been configured that way. Who configured your SMTP?

i didn't get you.

i am not using any smtp client.

I am using vb.net /asp.net to directly connect to gmail smtp server and send mails.
