I recently did a reinstall of FreeBSD on my web server (hard drive died) and I decided to upgrade from 4.11 to 5.4. Anyway everything is working fine except for this odd sendmail issue. So the info. I have two servers. 10.0.0.1:extranet.dalegroup.net: DNS and Mail (Windows 2003) 10.0.0.3:metro.dalegroup.net: Web Server (FreeBSD 5.4-Release, with sendmail) The web server box points to extranet for DNS. Now for my domain the internal setup is that the MX record for dalegroup.net points to extranet.dalegroup.net. Which is fine. But whenever I send mail from the web server to say someuser@dalegroup.net it cannot do a lookup.

Sendmail doesn't seem to want to send to the dalegroup.net domain, or the domain it is part of. If I modify the DNS and have my MX record on dalegroup.net to point to extranet.dalegroup.ORG (different domain, points to same IP) it works. Ideas?! Thanks :) P.S I didn't have this problem on FreeBSD 4.11. Sendmail hasn't be touched. Also some other info: metro# cat resolv.conf domain dalegroup.net nameserver 10.0.0.1 metro# cat hosts ::1 localhost.dalegroup.net localhost 127.0.0.1 localhost.dalegroup.net localhost 10.0.0.3 metro.dalegroup.net metro 10.0.0.3 metro.dalegroup.net. -- Michael Dale
