Hi,
we have an M650 hosting the ISQuarantine.
As a some of the Mailservers behind our AntiSpamSystem don't have LDAP and just send NDRs when mailboxes don't exist, the M-Series hosts many mailboxes that don't even exist.
As notification in the morning was such a mail storm, that our C350 cluster was busy for over 30 minutes, we have now installed a dedicated C100 just for relay of ISQ notifications.
As the M650 doesn't have Mail Flow Policies, my question ist which settings would be save for the C100 to survice the onslaught or can I throttle the M650?
