In part one of How to Troubleshoot SMTP Errors, we reviewed email status codes, internal reasons for email issues, and troubleshooting steps to address those issues. In part two of this series, we will examine some of the external reasons for email issues. 

What is SMTP?

The Simple Mail Transfer Protocol (SMTP) is a communication protocol used to transmit email between corresponding email servers. Using an email client like Mac Mail, Outlook, Thunderbird, or web clients like Gmail or Windows Live, SMTP can send messages to an email server. Although SMTP was initially designed as an email transport and delivery system, it later encompassed the email submission protocols that are now in use by both the Post Office Protocol (POP) and the Internet Message Access Protocol (IMAP). The above-noted email clients use these protocols to retrieve email from an email server. When this system fails, it provides the means to identify and resolve SMTP errors.

Introduction

The most effective method to protect a server from sending spam is to prevent it in the first place. In this article, we provide several techniques to use to keep the server from sending out unwanted spam or junk mail. Typically, unwanted, and unsolicited spam email is usually bulk sent out to an indiscriminate list of recipients. Spam is often used for commercial purposes but can be sent out in massive volume by a botnet or a network of infected computers.

In this tutorial, we discuss the Apache .htaccess file and the many ways it can be modified and configured to suit your specific needs. We will be reviewing how to configure .htaccess redirects, rewrites, and add other customizations.

Let's say you have decided to change domain names or have one web address on your site that you want to redirect to a completely different location. Using a .htaccess redirects, you can send visitors to the new page or site automatically!

What is Thunderbird?

Thunderbird is one of the most widely used open-source email clients in the world. Mozilla originally developed the software in 2004, but the project waned in 2014/15, and Mozilla stated that they would only deliver security and maintenance updates in the future. Until recently, the community maintained the software when a Mozilla Foundation subsidiary, MZLA Technologies Corporation, took over. Today, the improvements in security and stability are very much appreciated, and since version 78, Thunderbird has built-in OpenPGP encryption technology enabled by default. Earlier versions used the available PGP technology, but it needed to be installed as a supplemental plugin. 

What is Tmpmail?

Tmpmail is a utility written in bash that allows a user to create and use a temporary email address for receiving emails from the command-line. Underneath the covers, the bash script uses 1secmail’s API to receive the emails. By default, email addresses are created at random unless a specific email address follows the --generate flag.

In this article we will briefly cover the basics of monitoring your server via WHM. By following this process you will learn how to find: service status, resource usage, and Apache stats.

What is 2FA

Two-Factor Authentication (or 2FA as it often referred to) is an extra layer of security that is used to provide users an additional level of protection when securing access to an account. 

While there are many ways to make sure your server is as secure as possible, there are some basic steps that we can take to increase security. Users with a Linux server can change their SSH port to something other than the SSH default port (22). The steps listed below outline how to change SSH port numbers and enable the change.

What is SMTP?

When you send an email, your email client and multiple servers on the internet use the Simple Mail Transport Protocol or SMTP to move that message around the internet and ultimately into the recipient’s mailbox.
