Hello,

Can anyone suggest how to handle th following problem:

1. I've changed userName and password attributes in <processModel> in
machine.config to make aspnet_wp.exe run under my local account.
2. But now the following code in my .aspx fails with exception:

using System.Web.Mail;

SmtpMail.SmtpServer = "mymailhost";
SmtpMail.Send("(e-mail address removed)", "(e-mail address removed)","test 2", "test message");

Exception:
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.

Any suggestions would be thankfully appreciated.

Now I'm certain about conditions up which this problem occurs and not:

1. No problem. SmtpMail.SmtpServer = "mymailhost" and username/pasword under
<processModel> are default (ASPNET account).
2. Problem.. SmtpMail.SmtpServer = "mymailhost" and username/pasword under
<processModel> are set to non-default (set to local or domain user).
3.No Problem.. SmtpMail.SmtpServer = "" and username/pasword under
<processModel> are set to non-default (set to local or domain user). The
email gets sent only when local IIS SMTP is running.

Can anyone suggest how to make the #2 working? I really need to use
non-local SMTP host for email delivery.

Thanks in advance,
Andrei Suvorov.
 
You will probably need to go into the SMTP Server management console. Go to
the IIS MMC snap in (ie. Start -> Program -> administrative tools ->
Internet Information Services), expand the nodes and look for "Default SMTP
Virtual Server".
Right click and select properties, choose the "Access" tab and have a look
at the "authentication" settings to make sure they will allow your
particular user to send mail.

I've checked - there are default settings. For example, anonymous access is
allowed.

I checked - all users are allowed to relay, but the problem still there.

Perhaps compare the group and security restrictions on the account you are
trying to use. Maybe it is not allowed to run as a service (or something
similar) in your local security policy which is preventing it from working.
