This article is for G Suite administrators. To manage your own groups, visit the Google Groups help.
You might get this message when emailing a group in G Suite:
"Message rejected by Google Groups. Please visit http://support.google.com/mail/answer/188131 to review our Bulk Email Senders Guidelines."
Typically, this means that other users have identified the IP address the message came from as sending spam-related messages. This will cause messages they send to bounce. Here are some ways to fix the problem.
Whitelist the sender’s IP address
If a group message you sent has bounced:
- Add the trusted sender’s IP addresses to the email whitelist.
Bulk mail from this sender will no longer be reported as spam.
- To identify which mail servers are permitted to send email on behalf of your domain, add an SPF record for your domain.
- Customize your organization's spam filters to create an approved sender list to bypass any spam filters.
Turn on Google Groups for Business
Compared to other types of groups, Google Groups for Business provides more control over spam. For more control over filtering, turn on Google Groups for Business.
Check your MX records
If you’re relaying mail through a non-Google mail server before sending to Google, you can use the Inbound Gateway field for your domain’s MX records. This field influences the behavior of reputation checks and SPF checks.
If your domain's MX records point to any other servers besides the Google-hosted servers:
- In the Inbound Gateway field, enter the sending IP ranges from the servers that your MX records are pointing to.
- Check that your MX records are correct.
Refer to Set up an inbound mail gateway.
- Prevent mail to Gmail users from being blocked or sent to spam
- Spam and abuse policy
- Understand Groups policies and limits
