When this problem happens, the email is coming from localhost, so it's allowed to relay. If the email address that is being delivered to is a non-local account, then postfix will always accept it, as it doesn't know whether or not the non-local account is deliverable. The only time that postfix gives 550 is when the non-existant user is in hornclan.com. And I know for a fact that I don't do anything like impose quotas, nor do I administratively enforce a 550 response on any valid accounts, nor do I suspect that 127.0.0.1 is going to cause a DNS lookup failure because I run a local caching only DNS server. Does that mean I'm 100% certain that 550 always means non-existant user, no, I'm not. But a sample of my logfiles indicates that the only time postfix has (up to this point) given 550 is if the user doesn't exist. >Does Postfix not offer a way to configure around the problem? I don't know. But it's worth looking into. Cheers, - Mark _________________________________________________ tmda-workers mailing list ([EMAIL PROTECTED]) http://tmda.net/lists/listinfo/tmda-workers
