Recent versions of sendmail's configuration file make this check on incomming mail. You have something in the queue on tucu that has a bad sender address in it (mike1123@2hb.ne) How it got there is the interesting thing. I'd guess someone that is authorized to use your system has a missconfigured mail client. If you had an open relay there would be many more than one log line like above :-) chris -- Chris Fedde 303 773 9134 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
