A pkt viewer that can tell me the version of a particular pkt and tell me if
it is valid pkt or not.

James Coyle is looking for this because we have been having trouble with some
pkts and looking for a solution. I think he is trying to identify the type of
pkt he has and then it can be tossed without error. It's all a little over my
head but I am searching for such a thing if I can find one I think it would
make his job easier.

I use pktview from husky. It's all I have but it doesn't tell me the pkt
version. James also has pktdump but it crashes and deletes the file. He also
has inspecta but that doesn't seem to read the pkt at all.

I'm going to pass this on to him and let him know where I got it. He may have
further questions for you.. I'm lost already.. :)

 ml> as for anomalies, i guess that depends on what one calls an anomaly...

Something that causes the tosser to do unwanted or unexpected things
especially if it disrupts the smooth flow of mail.
