Domino: how not to send delivery failures to the internet

A customer of mine made me a request: he doesn’t want a delivery failure with the indication that the user does not exist in the Directory to be sent back when someone outside his domain sends a mail to a non-existing address.

By default this non delivery report is sent, but you can easily change the behavior of Domino.
Go in the configuration document of the server, then  Router/SMTP -> Advanced -> Controls. Hold undeliverable mail: set to enabled.

This is the explanation of that setting
Enabled – When the Router cannot deliver a message, it leaves the message in MAIL.BOX rather than generate a delivery failure report
Disabled – (default) When the Router cannot deliver a message, it generates a delivery failure report

Sametime Proxy 11.5IF1 issues with iNotes integration

I updated the Sametime Proxy server 11.5 to IF1 for a customer, and the integration with iNotes broke.
When a user tried to start a chat with another user he received an error

I searched about this and I found some references to the Tomcat settings
org.apache.tomcat.util.buf.UDecoder.ALLOW_ENCODED_SLASH and org.apache.catalina.connector.CoyoteAdapter.ALLOW_BACKSLASH
looks like by default are set to false and this is the cause of the error. The URL you see in the image should be converted to sametime.company.it:8443/chat/conversations without the trailing part with the user name, but it doesn’t.

To resolve the issue edit the catalina.properties file in the sametimeproxy/conf directory and at the bottom add those two lines

org.apache.tomcat.util.buf.UDecoder.ALLOW_ENCODED_SLASH=true
org.apache.catalina.connector.CoyoteAdapter.ALLOW_BACKSLASH=true

Restart the Proxy server and the chat works from iNotes.
