Does anyone know of a command (or command job) that can be used to bulk
remove a list of subscribers from a mailing list?  Perhaps something along
the lines of this command syntax for bulk additions:

QUIET ADD listname DD=X IMPORT
//X DD *
internet-address1
internet-address2
/*

(Replacing "ADD" with "DELETE" here doesn't seem to work.)

Thanks for any ideas,
