I’m trying to create a new Firefox Sync for a family member and the email they are using for it is a business email. When trying to sign up Firefox said the email was bounced and to check the address. We know the address is right because we received the email code. My guess is that Firefox mistakes the auto reply email with a bounce back. As I said this is a commercial account so they have an auto reply setup (“Thanks for reaching out, we will get back to you etc”). Now I’m waiting for 15’ before I can try to sign in again because it locked me out. I understand the feature is supposed to be helpful but if you can’t reliably detect real bounce backs it should be disabled. If I can’t use this address to create the account because of this my options are: - Tell this person to create a new email - Ask them to disable the auto reply in their current email - Don’t use Sync at all

None of these options is desirable or practical.
