VB 6 and CDOSYS

I am trying to send email from a VB ActiveX DLL in COM+ on a Windows
2003 server using CDOSYS.dll. Occasionally I receive the following
error:

Error Number: -2147220960
Message: The "SendUsing" configuration value is invalid.

The fixes described by MS don't seem to apply to this situation. I
have tried creating a Configuration object and valuing the
SendUsingMethod (with cdoSendUsingPickup), but that doesn't see to make

a difference. The code that calls CDO is:

    mobjCDO.CC = strCc
    mobjCDO.BCC = strBcc
    mobjCDO.From = strFrom
    mobjCDO.To = strTo
    mobjCDO.Subject = strSubject
    mobjCDO.TextBody = strBody
    mobjCDO.Fields.Item(cdoImportance) = lngImportance
    mobjCDO.Fields.Update

    mobjCDO.Send

   What am I missing?

I believe it's saying that you don't have a local SMTP server, and so a
SendUsing of cdoSendUsingPickup is not valid. Sounds like you need to set
more configuration options and access an external mail server.

A local SMTP service is installed as part of IIS, as is CDONTS - which can
only access that local service. Does your machine have IIS installed.

Alternatively, check the cdoSMTPServerPickupDirectory and cdoSMTPServer.
Sometimes, even if you have a local SMTP service, the cdoSMTPServer field
needs to be forced to "localhost"

The server is running IIS 6.0 with the SMTP service running. The
server is on our company's intranet so we have SMTP pointed at a mail
forwarder as the smart host.

I tried setting the cdoSendUsingMethod, cdoSMTPServerPickupDirectory,
and cdoSMTPServer, but it still occasionally fails. It does not fail
often, maybe 1 out of 500 times, which makes it difficult to pinpoint.
I have not been able to make it fail under the same circumstances.

Maybe the server is busy at that moment, introduces a
delay ?

Set a trap for that error, repeat trying to send that
particular data, log the attempt as to which data in
particular failed, the time and compare to the server
side event log messages at that particular time.

Didn't look up the error message but guessing, maybe
the forwarder is busy, taking too much time, or maybe
it failed to deliver a message because a remote host is
down?

Hope this provides some insights.

Just a thought - Are you creating a message configuration object for each
message. I have discovered that CDOSYS is rather flakey when you don't.

I was able to trap an occurrence of the error and log the configuration
values. The SendUsing and PickupDirectory values were empty. In an
errorhandler I was able to modify the values and resubmit the email and
it worked. Previously when I had been setting the configuration values
I wasn't issuing an Update on the fields, so I guess it wasn't taking.
A question on the update - do I need to issue an update on both the
configuration object and the CDO.Message object or will one update on
the Message object suffice?

So as long as I explicitly set the SendUsing and PickupDirectory before
calling the Send method, it seems to always work. I don't like the
idea of having to hardcode the PickupDirectory path in my code, but
something seems to be causing the Message object to not be able to get
that info.

FYI - A new Message object (therefore Configuration object) is created
for each email sent.

Thanks.
