Creating a single outbound SMTP server for your Domino Domain

By Andrew Pollack on 03/24/2005 at 03:33 PM EDT

I get more questions about smtp routing than anything else. Here's some notes taken from a recent presentation I gave at LotusSphere 2005 that should help you resolve some of the problems. The idea here, is not to have all your Domino servers routing mail to the internet. Instead, let one machine do it, and block the smtp port on the others. That helps cut spam down, and prevents configuration issues resulting in accidental relaying.

Using a Single Internet Mail Gateway

Server Documents (all but the server that will route smtp):
Set “SMTP Listener” to Disabled
Set “Routing Tasks” to “Mail Routing” – but not “SMTP Mail Routing”

Create a “Foreign SMTP Domain” Domain Document
Route *.* to “OurFakeName”

Create a Connection Document
Type: SMTP
Source Server: The domino server with smtp
Destination Server: MAKE UP a name
Destination Domain: “OurFakeName”
Routing Task: SMTP Mail Routing

This method means you don’t even need TCPIP as a protocol on your other Domino servers, because the routing all happens using Notes RPC protocols to the one server with SMTP capability

What Really happens?

All the servers where SMTP Mail Routing is not a task, look for a route to send the mail. These servers see that *.* goes to the domain “OurFakeName” -- That’s the SMTP Domain Document’s Job. The router task on the servers see that one Domino server has a connection to the “OurFakeName” domain so they route the messages to that server -- That’s the connection document’s job. The server which is SMTP Mail Routing Enabled receives the mail in its INBOX and knows how to send SMTP mail directly, so it does.

Let me ask you.. I'm searching the internet for hours and did not find yet how
to solve this:

I have ASSP and POSTFIX running on same machine.
Its all ok, but when SENDING email, ASSP has a "delay".

Mr. Fritz, author of ASSP suggested to use this workflow:

If I understand it right, local or authenticated users in this new scenario
would connect direct to POSTFIX so that "ASSP delay" would not occurr.

I know you have nothing to do with all these ;-), but it seems to me that you
understand quite well theses things like "smtp flows and ports". So if you
could point me some tip....

Thank you in advance

Thanks to the fantastic work by John Curtis and his team, the node.js integration with Domino is going to be getting a rich security model. What we know is that a user's authorizations will be respected through the node.js application to the Domino server -- including reader names, ACLs, Roles, and so on. The way ......
