Wildcards in policies

I've tried adding in *abc@sendgrid.net as an external email address but the policy does not seem to be applying.

Documentation says that the policy applies to the SMTP From rather than the Header From (which in this case is annoying).

My gut feel here is that wildcards are not accepted in this section - which is annoying because I don't want the policy applying to ALL emails from SendGrid.

Anyone know if wildcards ARE or ARE NOT supported in this screen? If not, I'm not really sure what to do, because the email is going to BULK Quarantine and there's no other way to bypass BULK (allow lists are not honoured in determining BULK emails).
