Mass mailing in billmanager
 

I want to send news to my clients (there are not so many clients in my system now, I use a free version with about 30 active customers).
How can I get a list of clients withour servers or inly with domain names?

There is a "Client segments" module in BILLmanager. There, you can select clients based on different conditions. Once you create a group (segment) of clients, you can send them newsletters or notifications from the "Mass mailing" module
