I am writing a multipart mime decoder because the original one is so tied into
|
|
libmsg. This one is very simple. It will take a multipart/related message and
|
|
split it into N files writing them to nswebXX.tmp in the temp directory. It will
|
|
then have another mechanism for BASE64 bit decoding the necessary files and rewriting them
|
|
to the temp directory. This should be very simple. It will only handle 1 layer of parts.
|
|
It will search for "Content-Type: multipart/related;"
|
|
If it doesn't find it. then the whole thing is considered one part text/HTML.
