Does anyone present would like to assist in the analysis work? Aside from
this data graciously being offered, we have access to many other source of
spam data from Brightmail, Postini, and such. Any help with analyzing it
would help greatly!

Hello All Again,
I apologize for my absence, I have unfortunately been very understaffed
lately and have been very busy with various projects.
I have approximately 1/4 - 1/2 billion emails worth of data of varying
specifics and depth.
Please contact me directly: postmaster(_at_)BellSouth(_dot_)com if you are
working on
this aspect and we can work out the specifics.
Currently I block about 3/4 million messages a day.
Regards,
Damon Sauer

Sorry, my mistake - I got the error codes wrong. Mea Culpa.

What kind of spam volumes are you working with?
