[aclug-L] Re: telnet to mailserver.com.au 110, I get a message: Connection closed by foreign host

[Steven Saner <ssaner@xxxxxxxxxxxxx>]

My guess is that "TCP Wrappers" are killing the connection on the mail
server machine. First look in /etc/inetd.conf to see if tcpd is being
used for the POP service. Does it look like:

pop     stream  tcp     nowait  root    /usr/sbin/tcpd   <something>

The key is the tcpd (it might have a different path).

If the above is true then you need to look in /etc/hosts.allow to make
sure that pop access is being allowed from the hostname/ip address of
the client PC. You can also look in the logs for messages that
indicate why the connection is being terminated.

Good luck.
