Hi Olav

I did some tests with different email clients by forwarding it as

Unfortunately the clients add different content-disp, -type.
E.g. Evolution makes a content-disp inline whereas Thunderbird makes a
content-type rfc822.
I need to pares the email with perl in order to extract the original
email so I can verify the signature -

Any idea how to do that in a generic way (I use Mail::GPG).
