Okay I am trying to write an SMTP Event Sink using VB.NET and cdo/adodb.
So far I've gotten further than I hoped... But now I'm sort of stuck.
This really isn't' an ASP.NET or vb.NET question.. It's more of a email
standards question.

Has anyone dealt with email threading before? I know there are some
message headers like "thread-index" and "thread-topic" and "references"
and "inreplyto"... And of course the subject line.

I've done extensive searches on the msdn website and thru yahoo and
google to find information on thread-index. All Microsoft says is

[Original message clipped]


The format is like this: Ab7TEZtW04eKS19qTMukQad1gGNu3A

However nowhere on the Microsoft site or anywhere on the web (that I can
find) explains how it is computed and how to decipher or use this field
to do any sort of threading. I have no clue how its encoded or how to
decode it so it's pretty useless without that information. What
surprises me is reading a ton of RFC's on email standards and Usenet
messages and whatever you and there is no information to be found
anywhere... How can someone develop against something totally
undocumented? (ugh).

Does anyone have any experience or sample code on how best to implement
email message conversations for like a message forum or egroup?

Thanks in advance

You can thread based on the subject, though it isn't very accurate. The =
thread index you gave is likely encoded using base64 (looks like it =
anyway). There are some built in converters in the framework if you need =
them.

do a search for "thread", there's a section on the issue. (section =
3.6.4)
