Regex Tester & Validator

This Python regex matches standard email addresses by validating both the local and domain parts. It restricts the local part (before the @) to a maximum of 64 alphanumeric characters, including plus signs, hyphens, underscores, and dots. The domain section allows up to 255 alphanumeric characters and hyphens, followed by a top-level domain of at least two characters. It is highly useful for basic form validation where specific length limits are enforced.
