SMTP is a standard protocol which allows for the sending and receiving of electronic mails. The protocol is easy-to-use and supported by all major mail clients. The protocol features line-by–line transmission and an ending-of-data sequence which consists a new-line followed by a stop. The only caveat is that a line in the message body can contain only a period. If this happens the client sends two periods in the message body to the server. The server replaces it by one. This is called "dot stuffing".
Message ID
SMTP uses a Message Identifier to identify the original message. The identifier must also be machine-readable. It must adhere to the msg–id specification format. Typically, the identifier is a sentence or word that summarizes the message to let the receiver know its contents. A message comment can be added to the identifier.
Message body
The Protocol SMTP Message body is made up of many parts. The header line is the first. The SMTP header is a readable string containing a keyword, followed a colon, then a value. Some header keywords must be included, while others can be left out. The SMTP header must contain a To, From and Subject line. The SMTP header line differs from SMTP commands in that it is part of the actual mail message.
RCPT command
A mail relay host is identified by the RCPT command for protocol SMTP. Before sending the message, the relay host needs permission from server. A 354 response code usually indicates that permission has been granted by the server. Once permission is granted, the sender then transfers the mail data one line at a time. The contents of the message will be inserted into the mailbox by the recipient SMTP Server.
DATA command
The DATA command in the protocol Smtp signals the start of a message. The message is composed of a header and a body. If the message was received successfully, the server will respond with a 250 response code.
QUIT command
Sending a QUIT command can be used to end a session with SMTP. SMTP servers will detect the QUIT command, and issue a 221 message of goodwill to the recipient device. This message ends the TCP session between the sending device & the receiving device.
RCPT
The RCPT protocol is used to send SMS messages via the Internet. This protocol uses RFC822 in order to encode the contents of an SMS. It also requires a minimum of 256 bytes. Each SMS message has 160 7-bit characters, and 70 Unicode character. But, you can send longer messages. First, split the message in smaller parts. The next step is to encrypt your text message.
DATA
The DATA command begins the transmission of mail message bodies. The message body is sent line-by line to its destination. A single line of text can be added to the body. This is called dot-stuffing. This is called dot-stuffing. It occurs when two periods are sent by the client and a single period is returned by the server.
FAQ
What is Website Design Software and How Does It Work?
Software for designing websites is used by photographers, illustrators and writers.
There are two main types for website design software. Desktop apps are installed locally on your computer and require you to install additional software on your computer. Cloud-based solutions are hosted remotely on the internet and require no additional software on your computer, making them ideal 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 only from a desktop application because it is more convenient. Some people prefer to use the same tool, regardless of whether it is on a phone or a laptop.
Cloud-Based Solutions
Cloud-based solutions are a great option for web designers looking to save time and money. These services let you edit any type or document anywhere you have an internet connection. This means you can use your tablet to do some work while you wait for your cup of coffee to brew.
If you decide on a cloud-based solution, you will need to purchase a license. However, additional licenses are not required to upgrade to a newer version.
These programs are available for web page creation if you have Photoshop or InDesign, Illustrator, and other Adobe products.
Can I build my website using HTML & CSS?
Yes, you can! You'll need to be familiar with web design concepts and programming languages such HTML (Hyper Text Markup Language), CSS, and CascadingStyle Sheets. These languages enable you to create websites that are accessible to anyone with an internet connection.
Do I use WordPress?
Start small to create a strong web presence. If you have the time or resources to create a complete site, do so. A simple blog is a good option if you don’t yet have the necessary resources. As you learn to develop and design websites, you can always add new features.
It is essential that you have a primary domain name before you can start your first website. This will provide a point to which you can publish content.
Is it more likely to be hired as a web developer if I have a good portfolio?
Yes. You must have a portfolio to be considered for a job in web development or design. Your portfolio should show examples of your skills, experience, and knowledge.
A portfolio typically includes samples from your past projects. These examples can showcase your abilities. Include everything: mockups; wireframes; logos; brochures; websites and apps.
WordPress: Is it a CMS or not?
Yes. It's a Content Management System (CMS). CMS allows you control your website content using a web browser and not an application like Dreamweaver, Frontpage or Frontpage.
WordPress's best feature is its free pricing! Other than hosting, which you usually get from your ISP.
WordPress was originally designed to be a blogging platform. However, WordPress now offers many options including eCommerce sites and forums, membership websites, portfolios and portfolios.
WordPress is simple to install and configure. You must download the installation file from their website and upload it onto your server. Simply visit the domain name from your web browser, and then log in to the new site.
After installing WordPress on your computer, you'll need a username and a password. After logging in, you will see a dashboard that allows you to access all your settings.
You can now add pages, posts and images to your site. You may skip this step if you feel comfortable editing and creating content.
But if you'd rather work with someone, you can hire a professional website designer to handle everything.

What is website hosting?
Website hosting refers simply to the place that people visit when they visit a website. There are 2 types.
-
Shared hosting is the cheapest. Your website files will reside on a server belonging to someone else. Customers who visit your website send their requests via the Internet over to that server. The request is sent to the server's owner who then passes it on to you.
-
Dedicated hosting is the most expensive option. Your website is located on only one server. No other websites share space on the server, so your traffic stays private.
Shared hosting is cheaper than dedicated hosting for most businesses. With shared hosting, the company that owns the server provides the resources needed to run your website.
But there are pros and cons to both options. These are some of the major differences between them.
Sharing Hosting Pros
-
Lower Cost
-
It's easy to set up
-
Frequent Updates
-
It can be found at many web hosting providers
Shared hosting is often as cheap as $10 per month. Remember that shared hosting usually comes with bandwidth. Bandwidth refers to the amount of data you can transfer across the Internet. Even if you are only uploading photos to your blog site, high data transfer rates can still cost you extra.
You'll soon discover why you paid so much more for your previous host when you get started. The majority of shared hosts offer limited customer support. You'll be on your way after they walk you through setting it up.
A provider with 24-hour telephone support is a good choice. They will attend to any issues you have while you sleep.
Dedicated Hosting Cons:
-
More Expensive
-
Less Common
-
Requires specific skills
With dedicated hosting, you get everything you need to run your website. You don't need to worry about bandwidth usage or RAM (random access memory).
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 become an expert at managing your servers.
So Which Is Better For My Business?
It all depends on the type of website you are creating. If you are selling products, shared hosting may be the best option. It's very easy to setup and maintain. Because you share a server, you will most likely receive frequent updates.
However, dedicated hosting is the way to go if you want to build a community around your brand. You can focus on building your brand without worrying about handling your traffic.
Bluehost.com is the best web host for both. They offer unlimited data transfers per month, 24/7 support and free domain registration.
