I've just uploaded a new version of the Virtualmin virtual-server module, which fixes a bug in the SpamAssassin configuration. This bug manifests itself as a failure to validate domains and an incorrect Procmail recipe for each domain. There are no other changes, but because this effects all users that utilize spamassassin/procmail the upgrade should be considered a high priority.

To upgrade on Red Hat based systems:

yum update wbm-virtual-server

On SUSE systems:

yast -i wbm-virtual-server

And on Mandriva systems:

urpmi wbm-virtual-server
