What is the actual minimum length of an email address as defined by the IETF?

Question

I\'m specifically looking for the minimum length of the prefix and domain.

I\'ve seen conflicting information and nothing that looks authoritative.

For referen

Answer 1

The shortest valid email address may consist of only two parts: name and domain.

name@domain

Since both the name and domain may have the length of 1 character, the minimal total length resolves to 3 characters.
