Hello,

i have a question about domino using an addtional mailsystem for smarthosting.

Domino is the primary mailsystem using mydomain.com, and i want to lookup for users not within my domino directory to relay to a smart host (e.g. exchange).

The inbound/outbound mails are send/received from a fronted gateway.

The domino smtp outbound port to the gateway was changed from default 25 to port 26, because of gateway configuration restriction.

The setting within the configuration document to mysmarthost.org now also tries to connect via port 26, which is not a default.

My question is now if i could give the smart host a specific port to connect with - like mysmarthost.org:25 ?

Hi,

As of now Domino only supports one port(non-TLS)) for all SMTP traffic for outbound.

There is a enhancement request for it though.

Route SMTP email via multiple ports in same Domino server

Hi Alexander,

Good day!

I also setup on my test server with the same configuration as yours and the smart host does not work on port 25 , it is still trying to route on port 26 , thanks.

Alexander,

the outgoing port configuration is a per server setting.

If you need to go to the gateway using port 26 and to the smarthost using port 25, you could probably do this using two Domino servers and making them route emails that need to go to the smarthost to a specific Domino server.

Lets say server1 sends outgoing smtp email to gateway using port 26, and sends mail that goes to smarthost to a second server (server2) using Notes routing. (1352) . Once emails reach server2 (configured to use port 25 for outgoing smtp), they are sent to smarthost using port 25.

Some checks needed to make sure this is possible, but without further info, I cannot make sure this idea is applicable.

Hi Michalangelo,

in this scenario we get the mails directly via external smtp gateway and are moved to the smart host if the address was not found within domino.

We solved this by changing the outbound smtp port back to port 25 and we will receive smtp mails from gateway via port 26.

Thank you
