Allow Non-existent Domains

Mail which comes from a non-existent domain is automatically refused for the reasons provided here.

If absolutely necessary, you can allow a specific unresolvable domain through by following these steps:

1. On every CanIt machine, edit /etc/mail/access. Right *ABOVE* the line that reads:

   # DO NOT EDIT BELOW THIS LINE: CANIT MAY DELETE CHANGES BELOW THIS LINE

   add a line like this (user domain in question):

   From:this.example.com OK

2. On every CanIt machine, run:

   make -C /etc/mail

   /etc/init.d/sendmail restart
