You realize you're adding the EmailAddress validator twice here, right?
The first time passes no arguments to it, while the second does.

The second argument is a "breakChainOnFailure" flag -- basically, if any
validators appear *after* that validator, then none of the following
validators will be executed.

When you add the validator, pass a boolean true as the second argument:
$email->addValidator($validator, true);

The easiest way is to use translation adapters, and the easiest and most
performant of these is the array adapter. The manual details how to add
translation adapters to your form:
