How to Allowlist Incoming Sender

If you wish to receive mail from a particular sender regardless of the message content, you should add it to the Allowlist. You should only do this when you know the sender will verify their address and will only ever send legitimate safe content.

1. To access the Allowlist, you need to be logged in to the SpamBull admin center.
2. In the left menu, expand the tab Incoming – Protection Settings.
3. Click on Sender Allow list.

There are up to three tabs displayed:

• Sender Allow list – Domain – This tab allows you to manage the allowed sender list for mailboxes at specific domains. On this tab you can:
  • Add Allow list sender – Add a sender to the Allow list for a specific domain. See Add Allow list sender – Domain tab.
  • Import senders from CSV – Import a list of senders to add to the Allow list for a specific domain via CSV file.
  • Export senders as CSV – Export the list of senders to a CSV file.
• Sender Allow list – Admin – Anything applied on this tab applies to all domains for the selected Admin User. On this tab you can:
  • Add Allow list sender – Add a sender to the Allow list for an Admin. See Add Allow list sender – Admin tab.
  • Import senders from CSV – Import a list of senders to add to the Allow list for a specific domain via CSV file.
  • Export senders as CSV – Export the list of senders to a CSV file.
• Sender Allow list – Recommended/Inherited – This tab allows you to view any inherited allowed senders that have been applied by a higher level admin.
