Hi Jerry,
As for the CDO.dll , it is a Mail message component based on the MAPI
providers(work mostly as exchange client). While CDOSYS.dll is a standalone
library for SMTP messaging(not rely on the MAPI providers or exchange
server). Here is a knowledge base article mentioned the version information:
#Where to acquire the CDO Libraries (all versions)
http://support.microsoft.com/kb/171440
BTW, for the System.Net.Mail classes in .net framework, so far based on my
understanding, that namespace provide some classes for sending emails via
SMTP protocol. However, it doesn't support reading or parsing existing
email messages(file based).
Sincerely,
Steven Cheng

Subject: CDO.dll or cdosys.dll
Date: Thu, 14 Aug 2008 09:22:01 -0700
>
I am working on a program that gets mail messages from the default SMTP
server with iis 6.0 on windows server 2003. I am using the cdosys.dll in
the
>system32 directory. The reference Name is "Microsoft CDO for Windows 2000
Library".
On the machine there is a CDO.dll in the Program Files\Common
Files\System\MSMAPI\1033 directory.
The question is which one of these is the current dll. I also wonder if
there is better way to access mail messages in the SMTP server. Does the
dotnet framework have a object for this like system.net.mail that does
this.
>
I am using the objects:
Dim objDropDir As New CDO.DropDirectory
Dim objMessages As CDO.IMessages
Dim objMailMessage As CDO.IMessage
Dim MailAttachments As CDO.IBodyParts
Dim MailAttachment As CDO.IBodyPart
to get messages in the drop directory (.eml files) open them and get any
attached file.
Thank you
