[Mailman-Users] what effect does mm_cfg.py setting VERP_PERSONALIZED_DELIVERIES have if personalize (nondigest) is set to NO?

In mm_cfg.py I have these settings:

OWNERS_CAN_ENABLE_PERSONALIZATION=Yes VERP_PERSONALIZED_DELIVERIES=Yes VERP_PASSWORD_REMINDERS = Yes VERP_CONFIRMATIONS = Yes

In a list with personalize (nondigest) set to NO, does that mean that all personalization options, including those above are not in effect?

Next question:

If I set VERP_DELIVERY_INTERVAL = 1 in mm_cfg.py, does that override any list-specific settings, or any of the other settings above?

Last question:

# Set this Yes to activate VERP probe for disabling by bounce VERP_PROBES = No

It sounds like VERP_PROBES enhances automatic disabling by bounce. I assume I should enable it if I have VERP_PERSONALIZED_DELIVERIES=Yes. Is that correct?

Thanks
