How do I install Qpopper on RedHat v7 Linux with xinetd?
Create a file called pop3 in the /etc/xinetd.d directory that contains the following lines (adjust the server line to contain the path to the Qpopper executable, and the server_args line to contain any Qpopper command-line flags you wish to use; this example shows the executable located at /usr/local/lib/popper, and the -s command-line flag): service pop3 { socket_type = stream protocol = tcp wait = no user = root server = /usr/local/lib/popper server_args = qpopper -s port = 110 } Note that it may also be necessary to create an entry in the /etc/hosts.allow file such as the following: popper:ALL Additionally, the standard distribution of RedHat Linux 7.0 installs the file /etc/xinetd.d/ipop3 in support of its default POP3 service, which is likely to create a redundant POP3 references for the xinetd daemon. You may need to either delete the /etc/xinetd.d/ipop3 file or comment out its service pop3 line.
