Test, validate and match regular expressions
Matches strings that resemble an email address: a local part of up to 64 characters before the @, followed by a domain part of up to 255 characters that must contain at least one dot. This regex provides basic email format validation, suitable for quick client-side checks or filtering, but does not enforce full RFC 5322 compliance.
