I'm trying to setup what I thought was an easy email system. I have two offline computers, and I want to simply send SMTP traffic back and forth. I have tried postfix, sendmail, and exim. I am missing something very fundamental because I get the same error with all three. I can send email locally on both machines, which of course works pretty much out of the box. When I try to send mail to the other computer, I always get a bounced email stating "Unrouteable address". This is my setup: two computers named comp1 and comp2, running one of the MTAs mentioned above and mailx command line mail tool.
on comp1: -------------- echo "test" | mail -s "test" [EMAIL PROTECTED] ## works echo "test" | mail -s "test" [EMAIL PROTECTED] ## fails on comp2: -------------- echo "test" | mail -s "test" [EMAIL PROTECTED] ## fails echo "test" | mail -s "test" [EMAIL PROTECTED] ## works I have researched and found the usual options for disabling dns lookup, but I still get the same error. I have tried the following under postfix: * disable_dns = yes * setting mynetworks to include my network/mask I have tried the following under exim: * removed host_lookup entry * added sender_unqualified_hosts and recipient_unqualified_hosts entries * tried ignore_target_hosts entry Under sendmail there was a ACCEPT_UNQUALIFIED_?? entry that could be defined. Does anyone else have any information I can use to simply send emails between two computers? -thanks
