It is a high-performance email server that provides advanced features for managing and delivering large volumes of email. PowerMTA is not available for free and requires a license to use.

Quick Question: Do you really need PowerMTA? Since PowerMTA serves commercial purposes for large volume sending/hr. it is used by enterprise companies which means it is not cheap. I’d advise, if you are not an email marketing company or at least a high volume sender with a few tens of millions email list and traffic, I don’t think you should go with Powermta as that will be expensively overwhelming for you. Aside from expansiveness, you don’t even need it since you will be sending just a few thousand emails which can easily be handled by free open-source projects like postal, postfix, Exim, etc . Better still you can go with alternative cheap solutions like using SMTP services (Amazon SES, Sendgrid, Mailgun, Mandrill, Spark Post SMTP Service…) and then integrate with an email marketing application like mailwizz. Not let’s get into our PowerMTA Setup Guide in detail. Powermta setup Guide: Let’s get started. As I said earlier, there are two components of an email marketing system.

What is port 25 in a VPS server?Â

We are very much familiar with ports in physical devices, which can be a hole in your physical computer, phone, or any gadget that helps you to connect to an external device.

Examples of ports in physical devices Ports on physical devices can be the most popular USB port, Headphone or earpiece port, VGA port, LAN Port, Serial Port, firewall port, printer port, and the list goes on and on and on. The above-listed port only helps you to connect to physical devices. The topic we are talking about ‘What is port 25 in a VPS server’ you can see it is totally unrelated to physical devices. It totally has to do with computer networking or virtualization. What is port in virtualization? According to Cloudflare A port is a virtual universally accepted point where network connections start and end. In other words, ports are protocols this allows connections or traffic to pass from one computer to another, it doesn’t matter the type of traffic it is.

Today it’s still recognized by the internet-assigned numbers authority as the default SMTP port. But, there arises an issue of great concern. Port 25 is an unencrypted port for email transmission. This means that during the email transmission process, an unscrupulous person can intercept the email and maybe modify it. As a result, internet service providers, email clients and most web hosts have decided to block port 25 for all incoming mail. This will greatly help the to prevent spam and modified emails from passing through their servers. In general port 25 is very great for sending and receiving outgoing and incoming mail. Due to the unencrypted nature of port 25 transmissions, many hosting companies blocked it on their servers. Though we still have a few companies that allow port 25 open on their server. Such companies make it easier for private email marketers to send unlimited emails from their servers. And this isn’t even a criterion for them to send spam emails. They will always monitor you to see the kind of email, at what frequency, response rate, and IP blocklist. Keeping these in check will help them to see if spam emails are originating from you.

What is an A record in DNS: All you need to know
The concept of DNS is something that must be understood to ensure a proper understanding of the internet. Basically, this guide is gonna address the question ‘what is an A record in DNS?’ but before we dive in deep, let’s see what the concept of DNS looks like in the descriptive sense. Cloudflare described The Domain name system (DNS) as the phonebook of the internet. DNS helps to eliminate the hassle of memorizing IP addresses for each specific domain. Each domain that you see on the internet has a machine hosting it. This machine holds a public IP address through which resources and directories on that machine can be queried and located. We have different Internet protocols (IP), the internet protocol version 4 (IPv4), and the internet protocol version 6 (IPv6). IPv4 and IPv6 are strings of numbers and hexadecimal numbers, this makes it difficult to be memorized. Even when memorized it will be difficult to memorize different websites. Further Explanation of DNS So the real essence of the domain name system, specifically ‘A record in DNS’ is to help map your domain to the exact server IP address hosting it for the location of the right resources and queries. When the internet is accessed, our devices are auto-assigned an IP address that will communicate with the IP of the target server. Locating the receiving Ip means, your queries such as the location of resources, directories, and downloads have been processed. Your browser through the help of your DNS Provider will locate the relevant resources you are looking for. I normally call the browser the tool while I call the DNS the performer. Without the DNS of the receiving server being in place, those resources cannot be located when your browser queries. What are the different types of DNS Entries? The A record in DNS zone is one of the many DNS records we have. There are different types of DNS entries, here are a few of them: To learn more about the different DNS entries you can check out a full list here. You can also check out our SMTP crash course to see how the different DNS records apply to good email deliverability. Here are also the 3 DNS record that is a must configure for markers or anyone that send a message over the internet if inbox delivery is a priority. In this tutorial, we are going to be focusing on the A record, which is one of the most important records. What is an A record in DNS Zone? A record is short for ‘Address record’. It is the primary and the simplest type of DNS record. We have ipv4 and ipv6 versions of the internet protocol. It is important to specify that the A record holds the Ipv4. A record maps domain to IP address. As hinted before, the internet work on the basis of IP address matching. A local computer accesses the internet with a numerical IP address which it uses to communicate with the receiving server IP address. Though there has been some kind of confusion between nameservers and what is an A record in DNS. They both look pretty much have the same meaning but we will address their difference and misconceptions in our subsequent tutorials. A record point your root domain to the corresponding IP address. This helps to eliminate cramming the corresponding IP address for each website. When you type a website like j-insights.com, it will resolve to an IP address hosting it says 92.249.44.37. The internet protocol address version 4 controls makes up more than 94% of the internet traffic and is separated by a dot. There are more complex, advanced, and modern internet protocols known as IPv6. IPv6 is mapped using the AAAA record while IPv4 is mapped using the A record. How to add a record for your domain. Here we are going to be looking into how to edit or add an A record in the DNS zone using Bluehost, Namecheap, and Cloudflare. I believe going through the different platforms will give us a more understanding of what an A record is and how to implement it: How to add a record on Bluehost To add or update just login to your Bluehost account> go to domain> Manage domain> DNS> Add record>select A record. What is happening here is that you are pointing the domain hosting IP address to the root domain say J-insights.com. To achieve this we use the @ symbol. So, any place you see the @ symbol pointing to an IP address, just know that A record is at work. Hope you got the point now 😊 Now let us move….. How to add a record on Namecheap The method of adding or updating an A record on Namecheap is quite similar to Bluehost. It can point to a subdomain or be used to establish a redirect to a different version of a domain. See the picture below….. A record can be used to redirect from https://www.j-insights.com to https://www.j-insights.com. This is very important in SEO to have to ensure you have only one version of your website. This tells Google not to index different versions of your website. How to add a record on Cloudflare As you can see below, on Cloudflare there is no @ symbol which is the root point. This shows that in other to establish an IPv4 mapping between your domain and its corresponding host, you can either use the @ or just type the domain name in the supposed @ field. How long does it take for an A record to take effect? If you look at the descriptive pictures I shared above you will notice there is a TTL (Time to Live) factor in the A record field. This denotes the average time in seconds that it takes A to take effect if updated. This average time is 14,400secs or 240mins. Importance of having multiple records. In my experience, it is a good practice to use
