Checking success/failure of sending CDO.Message

Tech-Archive recommends: Fix windows errors by optimizing your registry

Hi, I have been searching all over the internet and MSDN for a simple
answer and have found none...
I have some ASP/VbScript code (that I didn't write) to send an email
from a Win2k server:
--------------------------------------------------
set iMsg = CreateObject("CDO.Message")
iMsg.To = toEmail
iMsg.From = fromEmail
iMsg.Subject = subject
iMsg.TextBody = message

on error resume next
Dim iCong, Flds, serverError
serverError = -2147220973

set iConf = CreateObject("CDO.Configuration")
set iFlds = iConf.Fields

'Set the CDO configuration fields to send mail on specified external
smtp server
iFlds.Item("http://schemas.microsoft.com/cdo/configuration/sendusing";)
= 2
iFlds.Item("http://schemas.microsoft.com/cdo/configuration/smtpserver";)
= anSMTPaddress
iFlds.Item("http://schemas.microsoft.com/cdo/configuration/smtpconnectiontimeout";)
= 5
iFlds.Update

Set aMessage.Configuration = iConf
aMessage.send

if err.number = serverError then
'redirect to message-failure-page
else
'redirect to message-success-page
end if
--------------------------------------------------
Simple enough. I have found the the serverError variable corresponds to
a value on this page:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cdosys/html/_cdosys_imessage_send.asp
In hex, this value corresponds to the CDO_E_FAILED_TO_CONNECT error.
Now the problem is that, as you can see, there are many other possible
reasons for Send() to fail. Obviously, I don't want to check for all of
those error codes.

This page:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cdosys/html/_cdosys_imessage_send.asp
Isn't much help. Does send() return any value???

This page:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/e2k3/e2k3/_cdo_imessage_send.asp
Says that it returns S_OK if successful, but I don't know how to import
this value, and besides that, I'm not sure if this page applies.

I don't care if I know the specific reason, I just want to know if
there *was* some kind of failure, and do this check in a reasonable
fashion, preferably by not hard-coding a bunch of numbers...This all
seems ridiculous to me. Why is something so simple so difficult?

Help! :(
