(?:[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*
| "(?:[x01-x08x0bx0cx0e-x1fx21x23-x5bx5d-x7f]
| \[x01-x09x0bx0cx0e-x7f])*")
@ (?:(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?
| [(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?).){3}
(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?|[a-z0-9-]*[a-z0-9]:
(?:[x01-x08x0bx0cx0e-x1fx21-x5ax53-x7f]
| \[x01-x09x0bx0cx0e-x7f])+)
])
