Lately when I send a msg  to a mail list and then receive the msg back I
get the above with the following:
gpg command line and output
/usr/local/bin/gpg --batch --no-tty --status-fd 2 -d
gpg: Signature made Sat 04 Jan 2003 10.50.53 AM CST using DSA key ID
gpg: BAD signature from "David Barrow (Het Troll) <"

Could someone please help me with this.
