Sending mail to other hosts works. Receiving mail does not: Between host1 (non-freebsd) and host2 (freebsd 7), sending a mail from host1 to host2 (both in domain .domain.topdom) results in message 'Returned mail: see transcript for details": ----- The following addresses had permanent fatal errors ----- ----- Transcript of session follows ----- 550 5.1.2 ... Host unknown (Name server: mailhost.domain.topdom: host not found) ------------- host1 and host2 are both behind a firewall, but they are in the same zone (so firewall rules do not apply), both are even connected to same switch and their IPs are in the same subnet. Both have fixed IP address (not DHCP) mailhost.domain.topdom does not exist in DNS, but host1 can send mail to other mailservers all over the world. host2(FreeBSD): /etc/nsswitch.conf hosts: files dns /etc/resolv.conf domain domain.topdom nameserver UUU.VVV.WWW.ZZZ (correct ip address of a DNS nameserver) DNS is fully working on host2 (and on host1) According to the FreeBSD handbook I should be able to receive mail ? What can be missing here, how to remedy?
