The regex pattern ^[a-z][\w\-.]*@[a-z]+\.[a-z]{1,3}$ is used to validate email addresses. It requires that the username portion of the email address starts with an English alphabetical character and can contain any number of alphanumeric characters, hyphens (-), periods (.), and underscores (_). The domain and extension portions of the email address must contain only English alphabetical characters, and the extension must be 1, 2, or 3 characters in length.

for _ in range(int(input())):
    parser = email.utils.parseaddr(input())
    email_pattern = r"^[a-z][\w\-.]*@[a-z]+\.[a-z]{1,3}$"
    match = re.search(email_pattern, parser[1], re.I)
    if match:
        print(email.utils.formataddr(parser))
