  Bouncer is experiencing problems with verifying Yahoo/AOL/Verizon email addresses. Currently Boucner returns risky-low_deliverability to most of the verifications, as Yahoo is set-up as catch_all, and our deep verification of catch_all for Yahoo is malfunctioning. We are investigating the options for the fixes.
