No, and the answer is in your logs. Of course Google may refuse to
accept some messages, for some or all recipients to which the message
was addressed. They may also limit the "From:" address and or envelope
sender to match the login account. Is this is a personal email account
or a Google Apps (G-Suite?) domain account?
What happens to each message (and message recipient) is not a secret,
the delivery status is recorded in your logs.

The answer is in your logs.
