I run Mautic for our marketing platform and we have an issue with the bounce management for E-mail not working as it should.
If an email is bounced back, mautic sees the email, however it does not process the email as a bounce and change the lead list to bounce and mark the user as bounced.
Please DO NOT bid on this is you do not know Mautic and if you don't know how to fix this quickly and easily.
