I think it would be nice. But there is a however. I just tested the
setting with gnus and mozilla-thunderbird,  and  3 smtp server: my
university server, gmail and gmx.net. That is I sent a message to myself which
I signed pgp mime.



    -  My university server does not  not chance the header and the
       above setting would work.

    -  Gmail however produces the following header
Content-type: text/plain; charset=ISO-8859-1
Content-transfer-encoding: 7bit
X-Accept-Language: en-us, en
DomainKey-Signature: a=rsa-sha1; q=dns; c=nofws;       s=beta; d=gmail.com;
	h=received:message-id:date:from:user-agent:x-accept-language:mime-version:t
	o:subject:x-enigmail-version:content-type:content-transfer-encoding:sender;
	b=UQVmgpAvZMgBNilVC6jL3nU/UK+s/0Q0I4bMqo0fMedsguRm+vGvV1+rAc2djkQSsLsFU/agS
	JwEwzSgQ6gA+Uk8g8aiS9lz6d0r5TbnHNOloUC1gC/ig6Dyj7Juze5pjcmBqU9sVYyRWIgAz+2K
	LkImPJ1DR+sM5GAbWfIYWHo=


    -  Gmx even changed the content-type to
       Content-type: multipart/mixed; boundary="=-=-="


So I am not sure what is the best strategy. May be to include all of
these headers?
