Yes its possible to send email from anyone’s email id if SPF record for domain is not set.

What is SPF?

SPF is an open standard created to stop forgery of FROM addresses. SPF helps mail servers distinguish forgeries from real mail by making it possible for a domain owner to say, “I only send mail from these machines.” That way, if any other machines try to send mail from that domain, the mail server knows that the FROM address is forged.
This means is SPF record for Bill Gates email id is not defined anyone can send email by Bill Gates ID.

Implementing SPF for all email ids in organization may be difficult. But for higher authorities (MD, CEO of company) SPF record must be set.

SPF record can be added by informing you domain name provider to SPF record by providing required details.
