Yes it did say "no mail for xxx". So what is that mean? Most of the servers works fine with mailx command(display server's email address-root@xxx.com in from field). Only one of the server giving me this problem. I was wondering do mailx use some kind of header file(which has host email address)? I mean how do mailx process/get host's email address while sending mail. Unfortunately all of our BCV scripts use mailx, so I can't use mutt.

Thanks,
NS.
