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
