Question

What is the maximum length of a valid email address? Is it defined by any standard?

Answer 1

The other answers muddy the water a bit. Simple answer: 254 total chars in our control for email 256 are for the ENTIRE email address, which includes implied "<" at the beginning, and ">" at the end. Therefore, 254 are left over for our use.
