Can yahoo mail have a period in an email

According to Yahoo's official documentation, Yahoo Mail does allow periods (.) in email addresses. In fact, periods are a standard character in most email addresses.

For example, you can create an email address like [email protected] or [email protected], and it will work just fine.

However, it's worth noting that some email providers or systems might have specific rules or restrictions on the use of periods in email addresses. For instance, some older systems might not allow periods in the local part of the email address (i.e., the part before the @ symbol).

But in general, Yahoo Mail and most other modern email providers should be able to handle email addresses with periods just fine.
