The mynetworks has been set to 127.0.0.1/32.
I have not checked the firewall. Is there a command I can put in the
main.cf to check for spoofed IP's? Is there a way I can get it to not
accept mail -- period?
Thanks,
Steve

Again, I'd set mynetworks to 127.0.0.1/32 , so you're ONLY accepting
mail from 127.0.0.1 , not 127.*.*.*
Also, have you set your firewall to check for spoofed IPs? E.g. someone
on your external interface claiming to be 127.0.0.1 ?
Try sending mail through it from somewhere else on your lan - does it work?
