We run Postfix with default smtp connection limit = 100, when the limit is reached and another request comes in, it seems Postfix does not reject it explicitly, instead, the request is put into a queue.
This is causing problem on our firewall, because it considers the connection is being set up. If Postfix is under attach with a lots of connection requests, the firewall goes down first.
Is there a way to force Postfix reject the additional requests when the connection limit is reached?
Thanks a lot.
