How can I check reverse dns. My server is behind a Linksys router. It
does nat and dns.

Qmail doesnt' check with /etc/hosts.
Sounds like you may not have reverse dns entries, Does the machine you
are connecting from have reverse dns? Is it on the same 192.x subnet?

If I "telnet localhost 110" from the server I gain access immediately.
But if I use IP or hostname it takes forever from the server or from the
clients. I have checked hostname, /etc/hosts??? It eventually does
work but after a few minutes.
