Mailboxes Tab

Mailboxes are for the reception of email and do not provide access to the Spam Experts Control Panel. For an end level user to gain access to the Dashboard, an Email User must be created, see Manage Email Users.

In the General section of the menu, select Mailboxes Overview or Mailboxes Configuration, then the Mailboxes tab. At Admin level you can view all mailboxes set up in the system for all domains. At Domain level you can view all mailboxes in the domain only.

View mailboxes

In the Mailboxes tab, click on Show Results to view all mailboxes. To search for specific mailboxes, use the Query Rules panel to refine your search and click on Show Results to display matching results.

Add mailboxes

Add Multiple Mailboxes Via CSV

You can add multiple mailboxes at once by using the Import mailboxes from CSV feature on this page. You may export mailboxes as well by using the Export mailboxes as CSV feature here too.

To get the structure of the CSV required:

  1. On the Mailboxes page, click Export mailboxes as CSV

    This will provide a CSV file with the correct header columns

  2. Once you have this, populate this with your data
  3. Save the file
  4. Use Import mailboxes from CSV to upload the list to your domain

Add Single Mailboxes Manually

If you have Automatically populate the list with mailboxes determined as valid by the destination mailserver... enabled, mailboxes will be detected and configured automatically but you may want to add and customise the behaviour of specific mailboxes.

Please be aware that you cannot use non US-ASCII characters in the local part of a mailbox.

To do this follow these steps:

  1. Click on + Add mailbox
  2. Enter the Mailbox name (email address local part) - If you are at the Admin level also select the domain. If you are at the domain level, this will be automatically selected
  3. The following settings are optional

  4. Select a Timezone - Using recommended settings here will use settings from the Configuration Tab
  5. Choose an appropriate Date format - Using recommended settings here will use settings from the Configuration Tab
  6. Choose an appropriate Time format - Using recommended settings here will use settings from the Configuration Tab
  7. Select whether this mailbox should be Filtered for incoming mail - Using recommended settings here will use settings from the Configuration Tab
  8. Select whether this mailbox should be Archived
  9. Select whether this mailbox should have Automatic Email Scout Reports enabled
  10. Advise if this mailbox is a Distribution List - These mailboxes are not expected to send mail directly and so messages with a distribution list address as a sender may be blocked
  11. Set if the mailbox should disregard all legitimate email without a rejection response - This setting allows for no-reply@ style mailboxes, where all mail should be accepted but will not be read, and so will be immediately discarded
  12. Advise if this mailbox is a Shared Mailbox - A shared mailbox is a mailbox that multiple users can use to read and send email messages
  13. Save the mailbox - you will now see the mailbox added to the list for the domain

Plus Addressing/Sub-Addressing

Spam Experts supports plus addressing, often called sub-addressing, which allows the addition of a 'tag' on a mailbox by use of a '+' as the separating character. Such addresses should not be added to the mailboxes list, so long as the primary mailbox is.

For example: for the primary mailbox, plus addresses such as, or can also be used.

Delivery of mail at the destination server will be done to the full plus address, so the tag may be used for sorting mail in the inbox.

Please contact Spam Experts support to enable plus addressing on your Spam Experts Local Cloud Cluster.

If a mailbox was added used Microsoft 365 Sync, some settings cannot be edited.

Switch off Filtering for Specific Mailbox (Allow list recipients)

You can choose to Allow list a recipient by switching off incoming filtering on that mailbox.

  1. At Domain Level, select General > Mailboxes Configuration
  2. Click to open the Mailboxes tab and use the Query Rules panel to search for the relevant mailbox
  3. Click Show Results to see all matching results
  4. Click on the dropdown to the left of the mailbox and select Edit to open the Edit mailbox dialog
  5. Expand the Filtered (Incoming) panel and select No

  1. Find the mailbox you want to make into a mailbox alias from the Mailboxes list
  2. Click on the dropdown menu and select Convert mailbox to alias
  3. Ensure the correct domain is selected from the Domain dropdown
  4. Enter the mailbox name the alias should be attached to in the Mailbox box
