[ale] Stupid Sendmail relay question

[cfowler at mail.linuxiceberg.com (Christopher Fowler)]

I want to allow relaying from 192.168.1.0 and 209.44.70.0 on my RH 6 linux machine.  The sendmail faq tells me to put the domains in 
/etc/mail/relay-domains.  I did but still can not use the smtp server.

The contents look like this:

[192.168.1.0]
[209.44.70.0]
cereus.com
cereus-internal.com

I remeber that there was another file that needed the network numbers.
Can someone tell me what it is and were to specify it in sendmail.cf.

Thanks,
Chris
