We recommend that users in your organization use Gmail to review and manage spam messages they receive.
Use Gmail to manage spam messages
We recommend users in your organization manage spam with any of these Gmail apps:
- Gmail Android
- Gmail for iPad and iPhone
- Gmail web
Use these apps to identify and mark inbox messages as spam. This trains Gmail to mark similar messages as spam. You can also identify messages falsely marked as spam and move those messages to the inbox. This trains Gmail to identify similar messages as valid messages.
To let your users manage spam with Gmail web and mobile apps:
- Turn off the existing non-Gmail mailbox configuration so that users can open Gmail web and mobile apps.
- Turn off any mail delivery settings that route mail to an external mail server. Learn more about email routing and delivery settings.
- Instruct users in your organization to use Gmail to manage spam messages.
Learn what administrators can do when Gmail incorrectly marks some or all of your external incoming email as spam.
Although we recommend using Gmail to manage spam, one of these other methods might be more appropriate for your organization. These methods are intended for administrators only.
Route all mail to a legacy mail server
To improve spam identification, turn on spam and phishy headers in Gmail routing rules. If this setting is off, the legacy mail server might miss some spam messages.
