Hi, I have two domains. One the real 'ene.es' and the second the virtual 'gesida.com'. Both user@ene.es and user@gesida.com are allowed recipients. I want reject user@ene.es; as in sendmail, with "error:nouser No such user here" in the file /etc/mail/virtusertable. So, I will get only the user@gesida.com Reference: http://www.sendmail.org/virtual-hosting.html Regards, Davi Leal
