Incidentally, I have captured SMTP and POP3 sessions with Ethereal, ran them with "Follow TCP Streams", dumped the text to disk, and successsfully recovered the MIME or Base64 encoded documents attached to the email.

With HTTP, FTP, et al, it's a completely different story.

Not with Ethereal.

However, ethereal uses the same libpcap format for packet capture files
that tcpdump does; there are a number of tools that process libpcap
files, and I seem to remember somebody mentioning some tool on this list
that can do that sort of reassembly.

We should probably gather a list of all the tools people have mentioned
on the Ethereal mailing lists, and either add them to the "Tools"
section of the page at

        http://www.ethereal.com/links.html

or check which of them aren't already mentioned on the page at

        http://www.tcpdump.org/related.html

and add a link to that page from the "Useful Links" page on the Ethereal
site (actually, we should send the list of tools to tcpdump.org, add a
link to the tcpdump.org "Related Projects" page from the Ethereal
"Useful Links" page in any case).
