Re: telnet on local LAN question



You say you tried telnet to port 25 at <other>, have you tried it to
the IP-address as well? It seems unlikely this will work, as ping to
<other> resolves fine, but just to be sure.
On other, is there actually a mailserver listening on port 25?
Is there a firewall on <name> or on <other>?

If needed you can always use tcpdump to se what traffic is going out,
and what traffic is coming in.
