I found the Microsoft bloat stuff added to a mail message was enough
to increase its size 100 times:
$ munpack -t multipart_mail_ message
part1 (text/plain)
part2 (text/html)
$ ls -og part?
-rw-r--r-- 1 45 2005-06-09 08:43 part1
-rw-r--r-- 1 4641 2005-06-09 08:43 part2
to increase its size 100 times:
$ munpack -t multipart_mail_ message
part1 (text/plain)
part2 (text/html)
$ ls -og part?
-rw-r--r-- 1 45 2005-06-09 08:43 part1
