And you should post something constructive if you want to say something.

If you read the thread, I will AGAIN reiterate what I said: mailx can ACT like an SMTP server, in a basic sense. What I mean by that is that it makes the SMTP connection to the host specified next in the chain. The standard mail command can't, and needs to have an MTA to talk with to send the mail along to the relay host defined to it.

With mailx, you define your upstream account to your mail host, and it uses it to send messages, bypassing the need to define a relay in postfix/sendmail.

Again, mailx and msmtp both provide SMTP capabilities to talk to an SMTP server further upstream. The OP posted they wanted to use the built-in mail command WHICH DOES NOT. If they want to use it, they need to define a smart host, as I've said all along. If not, either of the other two work fine, and I've said that from the beginning, but you seem to ignore that. From post #6:
Sorry, its still not misinformation, no matter how many times you say it.
No, the links that are easily found with Google do that.
Except that what you've said is wrong; a client needs to talk to a server. Since what I posted has the benefit of actually WORKING that also indicates the validity of your advice.
Agreed.

That fact that a mail client needs to talk with a mail server (duh) does not mean you have to be running your own mail server!
What everyone is trying to tell you is: the mail client and the mail server DO NOT have to be on the same machine.

The fine gentlemen at google were kind enough to provide a mail server so that anyone can configure their mail clients with it and, thus, be able to send and receive email.

You ONLY need to configure your email client to use ANY of the multiple public email servers out there (like gmail, hotmail, etc...).

A slackware specific tutorial (that should work with any distro) on how to use ONLY a mail client (mailx in this case) to send and receive email through gmail took me 5 seconds to find on google.com (link here)

Is this thread a personal problem? kkkk!


1)I am using slack 14;
2) I'd like to use sendmail. But, after thread explanation mailx and sendEmail seems interesting in this simple start/stop server application; I am prefer mailx so its already installed.
3)I will use a external lan mailbox;
4)I only edit /sendmail.cf in:

# "Smart" relay host (may be null)
DSig.com.br



At the moment, I receive mails in my external mailbox. But it's a very long delay time. Why not a default immediately dispatch?

Refer to my post.

I read it, my dear! And I understood that rwalld is fast and a good schematic if I was using mail in local lan. But in my case I need a external mailbox so I edited /etc/rc.d/rc.sendmail and changed all -q25 entrance to -q5. Sent a mail at 10:00 am and I didn't received it yet.

Is sendmail working at the remote system? Does sending a mail to root@localhost get sent to root's mbox? Is the IP address of the recipient system correct?

No, what you wrote was what I quoted. mailx doesn't act like a server in any sense, basic or otherwise. The defining characteristic of a server in client/server architecture is that a server accepts connections from clients. mailx is a client, not a server. mailx doesn't accept connections initiated from other clients.

I'll also point out that in Slackware, /usr/bin/mail is a symbolic link to mailx. So you are talking out of your fourth point of contact in many ways.

How about you boys go outside if you are not going to help the OP?

/bin/mail or mailx are not mail clients, they are user front ends to sendmail. While it's not correct to say they are smtp servers, they expect to have a local server running in the background.

For a pure smtp client, use pine/alpine.

There have been multiple versions of mailx over the years. The one shipped with Slackware is the mailx which is part of the Heirloom project. It is most definitely a mail client. The first sentence on the project's homepage reads:



In a previous post you said you had you defined a smarthost of ig.com.br, but there doesn't appear to be any SMTP server running at that host. Are you sure you're using the correct hostname for your smarthost?

Now I have this output after some editings

/etc/rc.d/rc.sendmail start

Starting sendmail MTA daemon: /usr/sbin/sendmail -L sm-mta -bd -q5m
Starting sendmail MSP queue runner: /usr/sbin/sendmail -L sm-msp-queue -Ac -q5m
You have new mail in /var/mail/root


and

I tried a lot of possibilities using mailx, sendEmail and only sendmail. Received very lately messages. Then I think smart_host is correct.


This is my sendmail-slackware.mc. How can I fix it, so I am not receiving mails yet?

Problem is solved! I was trying to use it like a server. Then I tried to use like a client only and did another sendmail-slackware.mc for a client mode. Then I belive a changed line server for client in sendmail-slackware.mc edition was the point.

define(`confAUTH_OPTIONS', `A p y')dnl

Thanks a lot, Kustom42, eloi but specially Mike and TB0ne in this hard task!
