Handling reports of abuse, spam, and technical issues
For your convenience, Google monitors all email sent to the addresses email@example.com and firstname.lastname@example.org to ensure that we properly address reports of spam, abuse, and technical issues.
If you want particular users in your organization to receive email sent to email@example.com and firstname.lastname@example.org, you can create groups named abuse and postmaster in the Google Admin console. Members of those groups will receive email sent to those addresses, and the Google Team will continue to receive the email as well.
Because abuse and postmaster are reserved group names, you can't use them as usernames or nicknames. Also, you can only create the abuse and postmaster groups using the Google Admin console. You can't create groups with reserved names using Google Groups (groups.google.com).
