Hi,

I know what your problem is. It came first into my mind when I saw
that you used diacritics in your message. Suppose „ex" is the message
from the site UTF-8 encoded. Then

cristi at hades:~$ export LANG=en_US.UTF-8
cristi at hades:~$ cat ex | gpg --verify
gpg: Signature made Sun 04 Nov 2007 12:09:09 AM EET using DSA key ID AB10E8D2
gpg: BAD signature from "Noiano <noiano at lavabit.com>"

However, if I convert this message to latin1:

cristi at hades:~$ cat ex | iconv -t latin1 | gpg --verify
gpg: Signature made Sun 04 Nov 2007 12:09:09 AM EET using DSA key ID AB10E8D2
gpg: Good signature from "Noiano <noiano at lavabit.com>"
gpg:                 aka "Noiano <noiano at x-privat.org>"
gpg:                 aka "Marco Didonna <marco.didonna at autistici.org>"

So, the problem is encoding mismatch. Enigmail seems to sign the
message as if it was written in latin1, but someone (either the
receiver or the sender) convers this message to UTF-8.

I suggest you switch totally to UTF-8 in Thunderbird. I personally use
this setting and haven't had any problems.
