Actually, if it is refused there are several possible problems:
1. It isn't installed. Do an "rpm -qa | grep telnet" and verify that telnet-server is installed. 2. It isn't being run. Check the /etc/xinetd.d/telnet file to make sure that it is not disabled. Also run "/etc/rc.d/init.d/xinetd status" to make sure that xinetd is running. 2. It is being blocked by the firewall on the box. Check your firewall config. 3. It is being blocked via hosts.deny . Take a look at /etc/hosts.deny and /etc/hosts.allow . >If you intend to use telnet, may I suggest using SSH (you need to load the >SSH services and this is on the CDs from 8.1 in RPM format).

The telnet installed by default in Mandrake 8.1 isn't secure, although there is a package somewhere for stelnet (I think that's the name) -- or a telnet going through an ssh tunnel. Of course, I would tend to agree that telnet isn't the most secure way of doing things. > >> >> I'm confused as to why I can't use POP3, IMAP, and telnet.

Nope. 110, which is pop3, is for remote access from a client to the mailbox on the server. It has nothing to do with the "delivery" of e-mail. Delivery of e-mail either when it is being sent or *received* is processed through smtp (which is handled, depending on your setup, by postfix, sendmail, qmail or something else). You can and should have 110 closed to the outside world (since it sends in plain text, just like telnet), leaving it open to just your internal network.
