Hi All,

My web application is sending emails using CDO object.

SMTP service is enabled and running on my web server.

I am Directly setting the SMTP address to our mail server IP address. It is sending mails to internal users but giving "Could not access 'CDO.Message' object" error when sending a mail to outside address such as Yahoo, Hotmail or Gmail etc.

Is there any setting need to be done on either IIS or Exchange mail server to send mails to outside world ?

Do I need to enable the SMTP virtual site on the web server ?

Help !!!

chk whether you imported
Imports System.Web.Mail

Import statement is there ...

it is sending mails within organization but failing when tryin to send mails to outside world ... like yahoo or hotmail address

thanks

ofcourse you need to enable the smtp virtual server in the web server.

also, can you post the error message u get.

SMTP service is running on the web server, but is there any other setting need to do to point this SMTP service to our exchange server.

it is giving "CDO.message fail" error.

I don't know why it is not sending mails to outside world and sending only within organization ...

It should be related with AV.

Ref :
"I tracked this issue down to McAfee VirusScan Enterprise 8.0 VirusScan Console, Access Protection, Properties, Port-Blocking tab, Rule:"Prevent mass mailing worms from sending mail" This blocks outbound access to any port 25 on the network. Edit button shows a list of excluded processes to which new processes can be added."

hi there, try this i have successfully done this,
first create four textboxes in a webform whose id s are like this
1.txtFrom
2.txtTo
3.txtSub
4.txtContent
now drag a button from toolbox to send mail
now try the following code

private void Button1_Click(object sender, System.EventArgs e)
        {
            SmtpMail.SmtpServer="localhost";
            mmsg=new MailMessage ();
            mmsg.From =txtFrom.Text ;
            mmsg.To =txtTo.Text;
            mmsg.Subject =txtSub.Text;
            mmsg.Body =txtContent.Text;
            mmsg.BodyFormat =MailFormat.Html;
            mmsg.Priority =MailPriority.High ;
            SmtpMail.Send(mmsg);

        }

Don't forget to include the namespace using System.Web.Mail;
also at the begining declare,after the start of the class
protected MailMessage mmsg;
i think SmtpMail.SmtpServer is something elseRegards
