No.
Why not? Because it won't work.
There is no "IP Packet" that contains the whole of an email: like everything else, they are broken across a number of packets, and all of them are required, in the right order, to build the email. There is no packet type which says "I hold email data" or similar which you can grab.

Sorry - back to the drawing board! :laugh:

hi sir
i agree that whole of the email content would not be in a single packet...but the whole of the email would be in the form of packets..cant i retrieve data of the eamils from those small chunnk of packet data???

Possibly - but you'd need to know which are email data packets, and the IP packet does not know, so it can't help you.
You would have to look at the dataflow a level or two higher in the pyramid - ANd even then it's not guaranteed - what if the email is picked up via a website, like gmail, or through AfterLogic web mail? Then it just looks like website data...
