Hi All, I am wanting to set up a bunch of EXIM servers in a cluster for both incoming and outgoing email.
What I am trying to find out specifically is about rate limiting. I need the ability to apply different classes of service for different IP addresses. That is, they will have different rate limits and connection limits. I understand this is quite easy on a single server, but how do I configure this on a cluster? For example, if IP 1.1.1.1 was assigned 2000 messages/hour. I have 10 EXIM servers behind my VIP.. How do I ensure that 1.1.1.1 can only send max 2000 messages/hour? It would be possible, on a 'per server' basis that they may make a connection to multiple EXIM servers within the hour which would give them a possible volume of 20000 messages/hour(2000x10 EXIM servers) Same theory for connection limiting. I really don't want to do this at the load balancer by using sticky connections that last for an hour. Is there any documentation out there that someone could point me to for setting up large clusters and enabling this kind of rate limiting? I guess I am asking is there a way for each EXIM server to know what the others are doing so as to make decisions on connections and rate limits?
