Outbound email Error string "Blocking Bounce Email addresses:..." getting ignoredIssue Customers sending email notifications to recipients who do not have existing user records in their instance may discover that sending emails to this external recipient suddenly do not get sent. Instead, those emails get ignored and the logs show an error that starts with "Blocking Bounce Email addresses:..." ReleaseWashington DCCauseThis particular error is thrown because their email has reached the limit of failed attempts to send notifications. Previous attempts to send emails to the bad recipient get processed for the first 9 times, but each of those attempts will receive a returned email from the mail server of the recipient email with a subject starting with "Undeliverable:..." and the email logs of that returned email may have messages, such as "Email set to ignored because of disallowed from address, email_address_filter_reason = Disallowed address", explaining why the email did not get sent. ResolutionThe issue can be resolved by going to the Bounce Email Address [sys_blocked_email_address] table, locating the email that was blocked, setting the Failed Count to 0, and setting the State column to New.
