connect to 127.0.0.1[127.0.0.1]: Connection refused

Hi All My Xserve with 10.5.2 suddenly stopped delivering mails to my users. The mail queue is just growing! I have not updated anything, but there was a power failure. Clients recive the following error message : [i]connect to 127.0.0.1[127.0.0.1]: Connection refused.[/i] The log files stopped. I've tryed to start amavisd manually but it is already loaded postsuper -r ALL tells me that 3047 mails are requeued. But nothing helps Any ideas? Thanks EDIT: postsuper -r ALL actually works but new mails are still queued... I made a script that sends this unix command once a minute! Can someone please tell me how to have new mail delivered to the users and not queued? Thanks
