We need to prevent a group of employees from emailing certain domains. Is this possible? I know that we can use SMTP Outbound Controls - Deny messages to recipients in the following Internet domains or hostnames:, but this is too restrictive.
Thanks

Subject: server rules
Use domino server rules to catch email “Any recipient” + contains + “thisdomain.com”. AND "Sender " + is + “thatusername”.
You might have to create multiple rules, because you can’t have mutliple AND Sender is…the logic will require the sender to be name AND name, which doesn’t work. Likewise, OR won’t work because it would be “thisdomain” OR “sender”, blocking everything of either variety. There’s just no other way to split it up, currently, except to use multiple rules. So, I hope you don’t have 50 people who can’t email thisdomain.
Don’t forget to run “set rules” on your server when done.

As a bit of a workaround…
You could get a moderatly small server & build it up using something like the EXIM mail routing software. Within that, you can establish very fine level tailoring of how you want to process in and outbound email.
You’d have this server as your real SMTP gateway (in and out) and list it as a “smarthost” for your outbound email from the Domino server.
There are also email gateway appliances available that filter viruses, spam, etc. that can be tailored fairly specifically and may suit your needs (plus be a big improvement in security).
Subject: you can try MK Email Size Limiter
From www.mknetwork.comHere you can define which recipients should be forbidden and the action happens in the workstation (as soon as the user clicks on SEND) so no NDR is generated and the user gets instant feedback.
It’s very flexible and you can define that a given set of users cannot send emails to another given set of addresses.
