You didn't say what your hostname is. What is the output of hostname --fqdn ? The message that generated this error: What was the content of the From: header and the To: header? Who is [EMAIL PROTECTED] and <[EMAIL PROTECTED]> ? YOu can try to set visible_name=linuxfreak.com into the smail config. And you may try out the header rewriting mentioned in http://www.debian.org/fom/137.html Ciao, Martin
