SMTP is a standard protocol for sending and receiving electronic mails. The protocol is easy to understand and is supported in all major email programs. It features line-by-line transmission as well as an end-of data sequence that consists of a newline and a full stop. A line within the message body must contain a period. If this happens, the client sends two periods (or more) to the server. This replaces one of the periods. This is "dot stuffing".
Message ID
SMTP uses a identifier message to identify the original message. The identifier must not be machine-readable, and must conform to the msg ID specification format. The identifier is typically a single word or phrase that summarises a message and allows the receiver to know what it is about. A message identifier may also include a text comment.
Message body
The Protocol SMTP Message bodies are made up of several parts. The first is the header line. The SMTP header line is a readable string of text that contains a keyword, followed by a colon, and a value. Some header keywords should be mandatory, others may be optional. The SMTP header line must contain a To line and a From line. It may also include a Subject line. The SMTP Header line is a part of the actual mail and differs from SMTP Commands.
Command RCPT
A mail relay host is identified by the RCPT command for protocol SMTP. This relay host seeks permission from the server before transferring the message. A 354 response code is usually an indication that the server has granted permission. The sender begins to transfer the mail data line-by-line once permission is granted. The message contents are then sent to the recipient via SMTP.
DATA command
The DATA command signalling the start of a message in protocol Smtp is the DATA command. The message consists of a header as well as a body. If the message has been received successfully, the server may reply with a 250 code.
QUIT command
To end a session using SMTP protocol you can send a QUIT Command. SMTP servers can detect the QUIT command and will issue a 221 "goodbye" message to the receiving device. This message terminates the TCP communication between the sending device, and the receiving device.
RCPT
The RCPT protocol is used to send SMS messages via the Internet. This protocol uses RFC822 as a code to encode an SMS message. The minimum bytes required for this protocol is also minimal. Each SMS message must contain no more than 160 characters at 7-bits and 70 Unicode symbols. There are other ways to send more messages. First, you must split the message into smaller ones. Next, encrypt the text message.
DATA
The DATA command begins the transmission of mail message bodies. The message body is sent line-by line to its destination. You can also include a single line in your message body, which is made up of only one period. This is known as dot-stuffing, which happens when the client sends two periods and the server replies with a single period.
FAQ
What is website design software?
The website design software can be used by graphic artists and photographers, illustrators, writers and others who are involved in visual media.
There are two main types for website design software. Desktop apps are downloaded to your computer locally and you will need additional software. Cloud-based applications are hosted on the internet. This makes them great for mobile users.
Desktop Applications
While desktop applications have more features than cloud-based options, they're not always needed. Some people prefer to work exclusively from a desktop app because they find it more convenient. Some prefer to use the exact same tool whether they're using a smartphone or a laptop.
Cloud-Based Solutions
A cloud-based solution is a good choice for web designers who are looking to save money and time. These services enable you to edit any document from anywhere with an internet connection. This means you can work on a tablet while waiting for your coffee to brew.
If you decide to go with a cloud-based service, you'll still need to purchase a license for the program. However, additional licenses are not required to upgrade to a newer version.
These programs can be used to create web pages, if you have Photoshop, InDesign or Illustrator.
What is responsive web design?
Responsive Web Design (RWD) is an approach to designing websites where content displays responsively on all devices - desktop computers, laptops, tablets, smartphones, etc. This allows users to view a website on one device simultaneously but still access other features such as navigation menus, buttons, etc. RWD's goal is to ensure that users view the exact same version of a website on every screen size.
A website that sells primarily through eCommerce would be an example of this. You want your customers to be able to purchase products from your store, even if they are viewing it on a phone.
Responsive websites will adjust their layout according to the device that is being used. The site will display exactly the same way on a laptop as if it were viewed on a desktop computer. The page will look completely different if it's viewed on your smartphone.
This allows you to create one website that works on all devices.
Is web design difficult?
Web Development can be challenging, but there are many resources online to help you learn.
You just need to find the right tools for yourself and follow them step by step.
YouTube and other platforms provide many tutorials. Online software like Sublime Text and Notepad++ is also available for free.
Books are also available in libraries and bookstores. Here are some of the most popular:
"Head First HTML & CSS" by O'Reilly Media
"Head First PHP & MySQL 5th Edition" by O'Reilly Media
Packt Publishing, "PHP Programming For Absolute Beginners",

How To
What is website hosting?
Website hosting is the place where visitors go to visit a website. There are two types.
-
Shared Hosting - This is your cheapest option. Your website files reside on a server controlled by someone else. Customers who visit your website send their requests via the Internet over to that server. The request is then handed to the owner of that server.
-
Dedicated Hosting - This option is the most costly. Your website is only accessible from one server. No other websites share space on the server, so your traffic stays private.
Shared hosting is preferred by most businesses because it's cheaper than dedicated hosting. When you use shared hosting, the company that hosts the server gives you the resources to run your site.
However, both have their advantages and disadvantages. Here are the differences:
Shared Hosting Pros:
-
Lower Cost
-
Easy to Set Up
-
Regular Updates
-
It can Be Found On Many Web Hosting Companies
Shared hosting is often as cheap as $10 per month. Keep in mind, however, that bandwidth is usually included in the price. Bandwidth describes the amount of data that can be transferred over the Internet. Even if you are only uploading photos to your blog site, high data transfer rates can still cost you extra.
You will quickly see why you paid so much for your former host once you have started. The majority of shared hosts offer limited customer support. You'll be on your way after they walk you through setting it up.
It is important to find a provider that provides 24-hour support. They will help you deal with any issues that arise while your sleeping.
Hosting dedicated:
-
More Expensive
-
Less is More
-
Requires Special Skills
You're getting everything you need with dedicated hosting to operate your website. You won't worry about how much bandwidth you are using or how much RAM (random Access Memory) you have.
This means you will need to spend more upfront. However, once your business goes online, you'll discover that you don’t need as much technical support. You'll be able to manage your servers effectively.
Which Is Better For My Business:
This depends on the kind of website that you want. If you only want to sell products, then shared hosting might be the best choice. It is easy to set-up and manage. And since you're sharing a server with many other sites, you'll likely receive frequent updates.
However, dedicated hosting is the way to go if you want to build a community around your brand. It allows you to focus on building your brand and not worrying about managing your traffic.
Bluehost.com is a web host that offers both. They offer unlimited data transfers per month, 24/7 support and free domain registration.
