Hi,
newer versions of Enigmail seem to have problems to verify signatures made by kmail. It was also reported here
http://www.thunderbird-mail.de/forum/vi ... &highlight
I sent an signed/encrypted mail with KMail/1.9.5.
Thunderbird 2.0.0.5/Enigmail 0.952 (Suse 10.2 x64) could decrypt and verify signature, TB 2.0.0.6/Enigmail 0.95.5 (Ubuntu 7.04) only showed "decrypted message", nothing about the signature.
kmail uses pgp/mime, I suppose.
cu, muzel
