We have our email hosted with Google Suite and 'Email Routing' is set to 'Remote Mail Exchanger.' Is there any benefit to enabling SMTP Restriction in WHM " Security Center?

  Hi, @msklut SMTP Restrictions is a feature in WHM that stops users from bypassing the mail server to send mail. You'll only receive mail from root connections, Mailman mailing list software, and mail transport agent (MTA) to remote SMTP servers by setting up restrictions. This service is useful because bypassing mail servers is a common practice of spammers. so you should enable it.

  WHM's SMTP Restrictions tool prevents users from sending mail without going through the mail server. Because spammers frequently bypass mail servers, this tool is beneficial, and so it's better if you enable SMTP Restriction afterward, you'll only receive mail from root connections, Mailman mailing list software, and the mail transport agent (MTA) to distant SMTP servers by configuring limits.
