rblsmtpd and firewall

[Roberto Samarone Araujo \(RSA\)]

I turned on my firewall and I looked at my logs when I found this message:

            smtpd: 975401579.539737 tcpserver: fatal: unable to figure out
port number for /usr/local/bin/rblsmtpd

        What's the port number and protocol(TCP or UDP) that rblsmtpd use ?

                            thanks,

                    Roberto Samarone Araujo
