After encountering the issue described in Unable to post by email by unregistered users, I was led to believe that I should configure our public support email address for a group rather than a category. However, I noticed a difference between configuring a custom incoming email address for a group vs a category.
For categories, I have the option to accept emails from anonymous users with no accounts.
However, I don’t have this option when configuring a Custom incoming email address for a group.
Is this not possible for groups?
