Indeed, that's the purpose. And it doesn't matter if you get the mail via 25 or 587. 587 is just a convenience. Any other access to use your server for relaying should not be allowed at all. I really suggest you sit back and read the postfix documentation instead of questioning and questioning in the blue air. It's an absolute standard postfix configuration that you just seem to have not been made aware for years. Kai -- Get your web at Conactive Internet Services: http://www.conactive.com
