Hi...

Looking for some help setting up sendmail. Just a couple questions..

1) is it possible to set up sendmail so that it uses user@ip_address 
instead of user@domain assuming that the machine it is running on does 
not have a FQDN associated with it, and if so, 

2) where would I set this up?

3) If sendmail can't do this is there another mail program that can?

Thanks

Greg
