Throttle M650 Quarantine Notifications

[Eisenhafen]

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?

I think that by default M650 is using very high number of concurrent connection to any destination. It might be good to reduce the number of concurrent outbound connections. It's not possible to change that via GUI but you can use 'destconfig' CLI command.

For your purposes it might be enough to have 2 or 4 concurrent connection, that would not kill C350 and the delivery queue will stay on M650.
