Lets first create a variable, so you can just copy/paste the code.
Replace mail.example.net with your telnet destination domain name.
export REMOTE_SRV=mail.example.net telnet start $ telnet $REMOTE_SRV 25 $ telnet $REMOTE_SRV 143 c = Client, this is what you will enter s = Server, response we receive. c: telnet $REMOTE_SRV 587 s: Trying 107.189.21.115... s: Connected to mail.example.net. s: Escape character is '^]'. s: 220 mail.example.net ESMTP Citadel server ready.

Your alias file
# /etc/aliases default: me@example.net
A php script to send mail
#!/usr/bin/php
<?php
define('TAB',"\t");
$user = $_SERVER['LOGNAME'];
$host = exec("hostname -f");
$from = $user.'@'.$host;
$to = 'sweety@example.net';
$subject = 'Testing msmtp';
$message = 'hello from '.
#!/bin/bash SENDMAIL=/usr/sbin/sendmail RECIPIENT=tosomeone@example.com FROM=me@example.com cat <<EOF | $SENDMAIL -t ${RECIPIENT} From: ${FROM} To: ${RECIPIENT} Subject: testmail some test text as body of the email. EOF
Why have more then one mail server? Or why even have a mail server at all, if you can use gmail? Well there are many reasons to have at leased one mail server, but having one on each server doesn’t make sense at all. I tried both ssmtp and msmtp, and decided on msmtp.
msmtp is an SMTP client. In the default mode, it transmits a mail to an SMTP server, which takes care of further delivery.
