Customize Your Emails with Spam Filter

An approved sender can be identified by the IP address, domain name, or email address that you want to receive email from, even though the identifiers are in public block list or in custom blocked list.

Customize Your Emails with Spam Filter

A spam filter is used to detect unwanted emails and prevent those emails from getting to the recipient's inbox. Emails sent to the sender is subject to Google's spam filters and by default the filters automatically move the emails detected as spam into a recipient's Gmail spam folder.

We can customize an OU's spam filters into:

  • ⇨ Be more aggressive for strict filtering for bulk email.

  • ⇨ Bypass mail sent from within your domain.

  • ⇨ Use approved sender lists.

Use an approved sender list

By creating an approved sender list, you can bypass any spam filters. Approved senders list can be created on email addresses or domain name. The Approve Sender settings can only be applied to incoming emails

Gmail checks the addresses or domain names against the From part of the email header. Gmail does not check addresses or domain names against the Return-Path in the Mailheader.  Because of this From must match an address or domain you entered in the list.

Sometimes spam emails are sent by approved senders. These emails are marked as spam and delivered to the recipient's spam folder. 

If an email from an approved sender contains a virus or is part of an email attack, Google's virus filters prevent it from reaching users.

An email from an approved sender can still be blocked by the sender's Domain-based Mails Authentication, Reporting, and Conformance (DMARC) policy.
