I see.... In that case it sounds as if your MTA isn't properly configured to prevent "relaying". I don't use Postfix, but maybe this link will help you to check your configuration to prevent unauthorized relaying. Also, it seems your host is being marked as sending SPAM and that you'll have to request it to be dropped from the list of the various organizations that have flagged your host. http://www.postfix.org/SMTPD_ACCESS_README.html may help.... Or, wait for someone that knows Postfix to give you a better answer. -- Never be afraid to laugh at yourself, after all, you could be missing out on the joke of the century. -- Dame Edna Everage -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
