I sent an email by Gmail to:
firstname.lastname@example.org , email@example.com and firstname.lastname@example.org
Shortly afterwards I received an email saying that the address email@example.com was not found and to please check for typos or unnecessary spaces and try again.
It did not mention whether the email was sent successfully to the other addresses or not.
If one domain is not found does the email still get sent on to the other domains ?
