It could be on your system, or it could be on the one that your system relays to when it sends the message on to the recipient. Where you find the configuration depends on what MTA you're using. If you're using sendmail, it's probably in /etc/mail/sendmail.cf and/or /etc/mail/sendmail.mc. If you're using postfix, it's probably in one of the files in /etc/postfix -- perhaps main.cf. Check your MTA's docuementation for whatever distribution of Linux you're using. -- -D. [EMAIL PROTECTED] NSIT University of Chicago
