The rules are for incoming port 25 connections, not outgoing port 25
connections. The port on the local machine for the outgoing
connection is not going to be port 25. As far as changing the
firewall to allow incoming port 25 connections, it is a checkbox on
the default firewall GUI that will open the connection. If your ISP
is not blocking outgoing port 25 connections, except to their mail
server, the stock setup of Sendmail will send mail to the Internet.
It takes a bit more configuration to use your ISPs mail server, but
not much.
You're nitpicking unnecessarily. I know fully well that the incoming
port needs to be opening, which is why I stated it as a point against
default sendmail startup. No regular desktop Fedora user will even
thinkg about su'ing, vi'ing, or even consider needing an MTA. They'll
open up Evolution or Thunderbird to send an e-mail.
Example: Your User-Agent shows you used Thunderbird to reply to my mail
and it travelled through a route that never included using sendmail. You
arn't even using it yourself.
If you have a mail server on your LAN, you can configure Sendmail to
use it without much trouble. It is also not that hard to configure
Sendmail to accept incoming connections. All it takes is editing or
removing one line, and regenerating the config file. Or if you are
brave, you can edit the config file directly. The change is fairly easy.
Why would a user who installed using the default Fedora method need to
do this? No one has given me an example. Just the fact that you can do
it, which I already knew.
P.S. Future responders can skip treating me like I just installed
Fedora. You're talking to an individual who has years of Unix
experience. I know what MTAs are for, what uses them, rules of jobs,
etc., etc. Please look at my original question from the standpoint of a
*default* Fedora install. What do sendmail and atd do for a default
Fedora install? In fact, what do they even do for other packages? I am
not asking this for my own benefit, but for the benefit of a regular
Fedora user. If you require their service you will know yourself and
have to configure and startup (chkconfig or whatever suits you) those
services. Don't use the "Just Because" clause.
