Inbound Email Allowlist and Blocklist

Published:

When handling emails, there are lots of opportunities for spam attackers to pollute your inbox, or in some cases, you may wish to allow only your organization’s users and not outsiders, all of which can be accomplished using our email whitelisting and blacklisting settings.

Check out this video tutorial.

Follow the given steps to enable these settings:

  1. Go to Admin > Emails > Configurations.
  2. Here, you can find the options to add whitelist and blacklist for the emails.

Allowlist

  • Use the allowlist to allow specific users or domains to access your BoldDesk and submit support requests.
  • If the same domain is used in both whitelist and blocklist, then allowlist will be considered as a priority and it allows emails.
  • You can use the allow list to add the email address to prevent the “no reply” email from being suspended. However, only the first email is allowed, and it will be created as a ticket. Subsequent emails will still be suspended to prevent email looping. If necessary, we can recover the email from the suspended list.

Blocklist

Use the blocklist to prevent specific users or set of users to register and submit support requests. In blocklist, two types of actions are performed as follows:

Suspend

  • It acts as a soft block. This means that the emails marked in this category would be generated as separate entries as suspended emails. You can find the tickets in the suspended ticket view page.
  • You can be able to restore or reject these emails by manually validating them.
  • You can block all emails or domains using the wildcard (*) symbol.

Reject

  • It acts as a hard block. These emails are denied, you cannot keep any logs for these emails.
  • The wildcard symbol is not supported for reject case.
