Integrating GPG with MIME and exmh?

[Michael Below]

Hi,

I just replaced Debian's GPG 0.4.3 with the new 1.0.0 version. Now I'm using 
GPG with exmh, and the integration was really nice until I removed the GPG 
Debian package. After that, writing signed and encrypted messages still works 
as good as it did, but the support for reading application/pgp is gone.

Looks like I have to add some appropriate lines to /etc/mailcap, but I don't 
know what to put there to make things work as good as they did. With the 
Debian package, signed messages would be displayed in clear text, with a 
button above them to check the signature... How do I do that?

Ciao
