White / Black -lists per domain restrictions
Added 4 months ago
Those features involve a modification of the Incoming MTA.
Using those will restrict the maximum number of recipients of a message for all the domains hosted on your cluster. This applies to incoming messages as well as to outgoing messages.
The limit will depend on your server, mainly the amount of RAM you have.
On the smallest configuration we recommand, you still could have 372 recipients for a given message.
