SMTP (Simple Mail Transfer Protocol) allows a total of 128 ASCII characters, which includes the standard printable characters (from space to tilde) as well as control characters. However, the actual envelope and header lines are limited to 7-bit ASCII, meaning only the first 128 characters can be used. Each line in an SMTP message is also limited to 78 characters for headers, with a maximum size of 10,000 bytes for the entire message.

How many types of ASCII Code explain it?
There are primarily two types of ASCII code: standard ASCII and extended ASCII. Standard ASCII uses 7 bits to represent 128 characters, including control characters, digits, uppercase and lowercase letters, and some symbols. Extended ASCII expands this to 256 characters by using the 8th bit, allowing for additional characters, symbols, and graphical representations, which vary by encoding system. Common extended ASCII sets include ISO-8859-1 and Windows-1252, which accommodate various languages and special characters.

Why ASCII has 256 characters?
ASCII, or the American Standard Code for Information Interchange, originally defined 128 characters, using 7 bits for encoding. However, the extended version, known as Extended ASCII, uses 8 bits, allowing for 256 characters (2^8 = 256). This extension includes the original 128 ASCII characters plus an additional set of 128 characters, which include various symbols, letters from different languages, and graphical characters. The use of 8 bits became a standard in many systems, accommodating a broader range of characters for diverse applications.
