This is a basic configuration... your current configuration is wide-opened for spamming.
Create a Server Configuration document (if you don't have one). Then go to "Router / SMTP" / "Basics" then Address Lookup and select "Fullname only" :
Router/SMTP Basics | ![]() |
Number of mailboxes: | ![]() |
SMTP used when sending messages outside of the local internet domain: | Enabled |
SMTP allowed within the local internet domain: | Disabled |
Servers within the local Notes domain are reachable via SMTP over TCPIP: | Always |
Address lookup: | Fullname only |
I would also suggest the following configuration to prevent from having Dead mail in your mail.box :
"Router / SMTP" / "Restrictions and Controls" / "SMTP Inbound control"
then set like this :
Inbound Intended Recipients Controls | |
Verify that local domain recipients exist in the Domino Directory: | Enabled |
Restart the router task on your server.
