Where:

sender = <user_ID>
permits CP special messages from the specified z/VM® user ID only. CP special messages are discarded if the specified sender does not match the sender of the CP special message. If the sender option is empty or not set, CP special messages are accepted from any z/VM user ID.

Lowercase characters are converted to uppercase.

To receive messages from several user IDs leave the sender= parameter empty, or do not specify it, and then filter with udev rules.
