I use Thunderbird(TB) to read the list emails. A little bit of search
did show me something which may explain why I didn't get the unsubscribe
signature at the end of signed messages(normal view).
For pgp signed messages, the headers show that the content-type
is(message-id I'm using <[🔎] 20050427235439.GB3342@mauritsvanrees.xs4all.nl>):
Content-Type: multipart/signed; micalg=pgp-sha1;
protocol="application/pgp-signature"; boundary="wRRV7LY7NUeQGEoC"
And the unsubscribe signature falls out of the boundary delimiters,
--wRRV7LY7NUeQGEoC in this case. The starting of the signed messages
contains the following headers:
--wRRV7LY7NUeQGEoC
Content-Type: text/plain; charset=us-ascii
Content-Disposition: inline
Content-Transfer-Encoding: quoted-printable
Which gives me the entire content within those delimiters in my message
read window. Nothing after the last "--wRRV7LY7NUeQGEoC--" is printed in
the viewing pane.
As for gmail, I notice that emails from them have different
content-type, for example:
Content-Type: text/plain; charset=ISO-8859-1 --> Has no unsubscribe
signature!!
Content-Type: multipart/alternative;
boundary="----=_Part_3926_26680682.1114700845120" --> has unsubscribe
signature but not visible in TB. Similar to the way the signed messages
don't show it.
Now it is interesting that both messags from gmail are ascii text
messages but with different content types. I don't know why they have
different content-types though!
