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

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

Answer 1

well the problem is really the question.. email depends on if it is sent over the internet, or within a closed system (eg intranet). over the internet, I believe x@y.zz is the shortest email possible (e.g. google's G.CN for china would result in the shortest email adress possible, e.g. i@g.cn, which is 6 characters long). on the intranet however, it is an entirely different thing, and i@y would be possible, which is just 3 characters long.
