Firewall Ports

Could someone please settle an inter-office argument? Will your network traffic be slower through a firewall on any other port other than port 80. In other words, is port 80 faster than any other port you open on the firewall. I say no. Thanks in advance for the help!

mconnect

mconnect(1)                                                        User Commands                                                       mconnect(1)

NAME

       mconnect - connect to SMTP mail server socket

SYNOPSIS

       mconnect [-p port] [-r] [hostname]

DESCRIPTION

       The  mconnect utility opens a connection to the mail server on a given host, so that it can be tested independently of all other mail soft-
       ware. If no host is given, the connection is made to the local host. Servers expect to speak the Simple Mail Transfer  Protocol  (SMTP)  on
       this connection. Exit by typing the quit command. Typing EOF sends an end of file to the server. An interrupt closes the connection immedi-
       ately and exits.

OPTIONS

       The following options are supported:

       -p port         Specify the port number instead of the default SMTP port (number 25) as the next argument.

       -r              "Raw" mode: disable the default line buffering and input handling. This produces an effect similar to   telnet(1)  to  port
                       number 25.

OPERANDS

       The following operand is supported:

       hostname        The name of a given host.

USAGE

       The mconnect command is IPv6-enabled. See ip6(7P).

FILES

       /etc/mail/sendmail.hf           help file for SMTP commands
