Huh? $ cat /etc/debian_version 3.0 $ cat /etc/resolv.conf search hpcc.sztaki.hu lpds.sztaki.hu sztaki.hu nameserver 127.0.0.1 $ ping rs2.lvs PING rs2.lvs.sztaki.hu (193.6.200.132): 56 data bytes ... It is definitely available in Woody.

That's very bad. Well, why do you have any search domains then? It is for human convenience only, and a mail server usually does not have regular user accounts so no need for such convenience features. > Sure, I can do that with telnet interactively.

That's what I'm seeing. For such setups I suggest running some local DNS-catching solution (nscd or a local caching-only name server).
