At first, Amazon SES are not marking contacts that are bouncing email back so I used Amazon bounce simulator and it wasn’t marking it bounce. I switched over to a different verified email and try again. It start marking bounces and even the bounce simulator email address was marked as bounce by Mautic so I thought all is good and for some reason one of my verified email wasn’t.somehow marking it bounce correctly.
Now it stopped marking it bounces and I tried the Amazon simulator email and sure enough again it not working. Here what I am seeing in the log … a bunch of same line each time when Mautic failed to mark it bounced
mautic.WARNING: Received SES webhook of type '' but couldn't understand payload []
Any idea what it mean and how to fix it? it was working fine before.
