Hi everybody,
One question : If I had a postfix smarthost set in my domino configuration will save resources? All smtp job will be made by the smtp but I need a connection between postfix and domino for delivering messages on mailboxes so if I enable a smarthost like postfix would I save resources considerably?

Yes, you would save considerable resources.
If Domino sends directly to the internet, it will make a connection per recipient. If you use a smarthost, Domino will only make 1 connection, the smarthost has to deliver the mails to all separate recipients.
cheers,
Tom

Ok, so if you enable the smtp rules on the smarthost you delegate on it the delivering jobs and then you get free resources on you domino machine… but is there anyway to making two fully independent mail systems such as ISP in wich you have an ip for pop and another for the smtp? how they communicate between them? has this last configuration something related to connectors (like postfix connector)?

But one question… when you enable a relay server or smarthost finally the mail and the connection has to pass over main domino server, in wich you’re generating the same trafic as it was the relay server except there were some mail destinations in wich domino only makes one connection am I wrong? And for example if you enable a smarthost finally it must deliver too to the “main” domino server for to deliverying on it’s mail file databases, so… is there any notable difference between having all on the domino main server or having the domino main server with smart and relay host when we talk about workload? Will the domino main server save resources notablily¿?
Thanks for you’re help
Hace a nice day

No. It is the Relay Host that saves resources in that way. The Relay Host is for outbound mail. The SmartHost is for inbound mail.
If a Relay Host is configured, then when Domino is sending outbound Internet mail to someone outside of its own Internet domain, it will send the message to the Relay Host no matter who the recipient is. This is useful for lowering the load on your primary server, but the main reason for having a Relay Host these days is probably to keep your primary server inside the firewall while still having a server that is in your DMZ (or outside your firewall) make all your outbound connections.
If a SmartHost is configured, when Domino receives inbound Internet mail it checks to see if the address matches a user in the Domino Directory. If there is no match, then the message is sent to the SmartHost. This is useful when you have a split environment with some Domino mail users and some non-Domino users. The SmartHost configuration allows you to configure your Domino server as the primary MX for your domain and forward any messages it can’t deliver on to a different mail system.
