    if running Iptables on a linux server, the following command should work:

    iptables -A FORWARD -p tcp --dport [Port Number] -j ACCEPT
    Code (markup):
    replace tcp with udp if need be and remove the brackets from around port number/replace with the necessary port.

    Hi,

    Default port for courier-imap : 143
    Protocol for courier-imap: TCP

    Default port for lighttpd: 80
    Protocol for lighttpd: TCP

    Default port for Qmail: 25
    Protocol for qmail: TCP

    You need check programs configuration files for the correct port number.
