In an attempt to address the situation of receiving unwanted notification emails directed to users that have been deleted from the Wasp Cloud system, we are implementing an internal email blacklist.

However, if a customer is disabling and enabling various users, this may cause an email address to inadvertently get added to the blacklist, so that if the user is reenabled, they will not receive expected emails.

The workaround for this situation is to first change the user's email address to a bogus value (for example, jsmith-disabled@example.com), then disable the user. Then when the user is reenabled, the email address can be restored to the proper value.
