Iptables and Logins at boot-up

[John J. Boyer]

Thanks to all who helped with the ssh problem. There were two gotchas. 
Iptables was blocking all connections, and password authentication was 
turned off. Now I want to use the target machine to receive mail and for 
backup. When I boot the target machine, iptables is on and I have to log 
in as root to turn it off. How can I set iptables to be off at boot time? 
Or, better, to accept ssh and scp only from the source machine?

Two user accounts receive mail continuously. I would like to have them 
automatically logged on at boot time. Is this possible? How?

Thanks,
John
