Postfix reverse name resolution problem

Hi guys,

My postfix on Linux fails to resolve reverse DNS of some hosts. When I look at the logs, I see that it rejects mails with message "unknown [] ... cannot find your hostname".

However, when I use "nslookup" from the shell to reverse-lookup the IP it has rejected. Resolution is working perfectly.

On my system Postfix has a chroot dir under /var/spool/postfix, and under that there's another etc/resolv.conf. I made sure it's exactly the same as the "real" /etc/resolv.conf. Still, it doesn't work.

Can somebody please suggest something?
