I have (setq mc-pgp-keyserver-address "wwwkeys.ch.pgp.net" mc-pgp-keyserver-port 11371 mc-pgp-keyserver-url-template "/pks/lookup?op=get&search=%s") To force a correct server and to force the new type of server. The best solution is to go load ftp.xemacs.org:/pub/xemacs/pgp-keys/martin_buchholz.asc and type M-x mc-snarf package-get-require-signed-base-updates Jan
