Failed to save enabled features : The procmail command

Virtualmin was updated this morning to 3.64. When an attempt is made to make any changes to Features and Plugins VM fails with the follow error:

Failed to save enabled features : The procmail command
/usr/bin/procmail-wrapper has 104755 permissions, when it should
be setuid and setgid to root. Email may not be properly delivered
